A free range or wild chicken's egg, (not from a chicken kept in a pen and fed a restricted diet) is a rich orange yellow. When it is cooked, its albumen is strong - it is a Super Egg! When hard-boiled, the shell has a hard time pulling free from the egg. Don't you hate that? Well that's a fresh egg! Fresh eggs are more active in recipes, almost doubling their thickening and bonding ability. Cakes are firm and moist, custards readily thicken, pancakes stay together. Pies firm up!
"Real" eggs are tastier than store bought eggs. And they taste great! They are more nutritious (due to the nice weeds, bugs, dirt and stuff). It's good that store-bought eggs are there for those that cannot have chickens, but if you can, any good cook who knows about this would certainly go for it!
People normally use chickens for egg laying for about 3 years, but chickens can lay for 5-6 years.
Chicken feed can also include Roxarsone, an antimicrobial drug that also promotes growth. The drug has generated controversy because it contains the element arsenic, which can cause cancer, dementia, and neurological problems in humans.
What do you need to raise chickens?
You need a coop or a cage that allows 2 square feet of space per chicken. Even more space is better. The more space you give your chickens, the happier and healthier they will be.
You can raise your chickens in a coop or in a large kennel like the ones built for dogs. If its situated on concrete, soften it up a bit with a bale of hay or grass clippings from your yard (just make sure the grass was not treated with insecticides, fertilizer, or any other chemicals).
The inside of your kennel or coop should have roosts for your chickens. A roost is a stick suspended about three to four feet off the ground that your chickens will sleep on at night.
