How many chickens can you fit in a cage? Devised in the 1940s, battery cages were a response to an increase in hen productivity as a result of major breakthroughs in nutrition and breeding (Duncan, 2001). The movement was toward greater automation with a goal of reducing disease transmission while increasing hygiene in the poultry industry. As a result, there was a huge reduction in the number of producers and an increase in the capital investment needed for egg production and processing (BC Egg Producers, 2001). This led to a system that produced the maximum number of eggs for the lowest possible price, as well as seriously compromising the welfare of hens. In a battery cage, the rate of food and water, and duration and intensity of light are tightly controlled. There is no access to the natural environment, nor any opportunity to conduct natural behaviours such as perching, dust bathing, wing flapping or nesting. These cages inhibit almost all the natural behaviours of hens (Rollin, 1995). Battery barns in Canada hold thousands of cages, each holding five to seven birds, in tiers of two to eight cages high, with farms averaging 18,368 birds (Agriculture and Agri-Food Canada, 2006). However, farms can range from anywhere between a few hundred to more than 400,000 hens. The average laying hen produces about 300 eggs per year (25 dozen).

回复: How many chickens can you fit in a cage?October 13, 2005 - Egg Production Exposé How would you like to be crammed in a cage with 4 others for a year, have your lips cut off, be covered in excrement, never stretch your arms or legs, never see natural daylight, and then, after 12-18 months, have your throat slit. That is what life is like for over 90% of Canada's egg-laying hens. See for yourself. ​ (Note: There are 20 seconds of blackness at the start of the video) SEE PHOTOS A battery egg "farm" is not a pretty sight. The reality is quite different from most people's expectation of a farm. This photo was taken undercover at a farm in the Guelph, Ontario area belonging to LEL Farms and owned by a veterinarian with connections to the University of Guelph. The pictures show birds covered in excrement and crammed into cages so small they can barely move. In battery cages, there is no space for hens to flap or stretch their wings. When they try, their wings sometimes become trapped in the bars of the cage. Vertical space is limited and hens are often unable to stand up fully and raise their heads without hitting the bars of the cage. Their beaks are sliced off with a laser or hot blade to prevent pecking at other birds. The birds are clearly suffering from extreme feather loss, and you will even see some escaped birds left to languish on a pile of manure three feet deep. Changing your purchasing habits will help change these farming habits. Buy certified organic eggs or choose egg-free alternatives.

回复: How many chickens can you fit in a cage?Animal welfare certified Canada BC SPCA Certified The BC SPCA is the only animal protection organization in Canada that has set up a program to assure consumers that the animal products carrying the BCSPCA Certified label come from farms that passed the BC SPCA’s animal welfare standards. These standards are based on those of the UK-based RSPCA’s Freedom Foods program and exceed the national recommended codes of practice set up by the Canadian federal government for animal husbandry. US & International Welfare Approved Animal Welfare Institute’s “Welfare Approved” program has the highest standards for the humane treatment of animals. AWI is a non-profit organization set up to reduce the amount of pain and suffering farm animals endure. On “Welfare Approved” farms, animals have the space to move around freely, socialize and conduct natural behaviours that are essential to their health. Certified Humane Humane Farm Animal Care’s “Certified Humane” program is the only certified label that requires the humane treatment of farm animals from their birth until their death. In the case of egg-laying hens, the birds have enough space to stretch their wings, enough food and water and proper shelter. HFAC standards require dustbathing, perches and have strict air quality requirements. Producers also must complete the food safety and environmental standards. Freedom Foods Freedom Foods is the animal welfare food label of the Royal Society for the Prevention of Cruelty to Animals (RSPCA). Located in England and Wales, the RSPCA is a leader in animal welfare issues and was the first organization in the world to introduce an animal welfare-based food label. Each certified farm must adhere to the strict standards that include each stage of an animal’s life. These standards are regulated on a yearly basis with random checks throughout the year and include animal transportation. Click here for our organic certification comparison chart.

回复: How many chickens can you fit in a cage?Farm fresh, Natural and Vegetarian A hen in front of the rising sun. A little red barn. Words like "fed vegetarian feed," "farm fresh" or "Omega-3." These words and images on egg cartons mean nothing as far as animal welfare is concerned. In fact, eggs in these cartons are from hens in cages. Omega rich eggs Despite their logos and the descriptive words on their cartons, Omega-3 and Born-3 eggs are from hens in cages. In order to achieve an omega-3 content similar to that found in eggs from free-range hens, supplements such as flax and fish oils are added to the feed of a battery cage hen in order to boost the omega-3 content in her eggs. Eggs from free-range hens have a naturally occurring level of Omega-3 due to the diet of natural vegetation and insects and grasses that free range hens consume. In 2007 CBC Marketplace analyzed the difference in omega oil content between certified organic eggs and Omega-3 eggs and found that amounts were negligible. The only real difference between these two types of eggs is that Omega-3 eggs are from hens crammed into tiny wire cages. However, in 2009, Karyne Rogers, of Geological and Nuclear Science's National Isotope Centre in Lower Hutt, New Zealand, compared different brands of off-the-shelf eggs from cage, barn, free range and organic farming regimes. Using isotope analysis, she found almost all the eggs could be differentiated by relating the carbon and nitrogen found in the egg to the hen's diet. This was possible as diet directly reflected the type of farming environment where the hens were raised, Dr Rogers said. In general, eggs are very poor sources of omega fatty acids. If you want to add omega-3 and -6 fatty acids to your diet, try some of the following high omega foods: Flax seeds (one of the richest food sources of omega fatty acids)Walnuts (very good source)Soybeans (very good source)TofuBaked winter squashSpinach High omega-3 and -6 oils include: Flaxseed oil (very high)Hemp seed oil (very high)Corn, canola, safflower, sunflower, soybean, and cottonseed oils For information on what labels to look for, see our list of Recommended Egg Labels or download our wallet-sized tri-fold Egg Shopping Guide.
