I have yet to encounter someone on this site that keeps diapers on thier chickens and keeps them in thier house. I think if such people exist they are few and far between. I reall don't think you can lump the people who keep diapers on thier chickens in the same group as people who have an attitude towards thier chickens as pets. I don't consider them the same as my dog...dogs are predators and have a complex mind unlike that of any other animal...Only horses have a history as connected with people as dogs. Dogs are capable of things that primates like chimpanzees are not, like communication thru eye contact with people. However, I don't buy into the "ranking" of animals as worthy of certain levels of respect or kindness based on my cultural experience with them. People who rank dogs as more worthy of respect and life than chickens are exhibiting a cultural bias. In china they would be looked upon as the same thing. I believe that all animals should be afforded respect as individual lifeforms and as keepers we should strive to ensure that thier days are happy, contented and that they do not die terrorized (as they are in factory slaughterhouses) or in agony (like the ones kicked like soccer balls in factory farms) even though they are already crippled by thier oversized bodies and are helpless.
My chickens are pet-like and I keep them for egg production. I don't eat them, and I don't eat meat. When you keep chickens for eggs as a protien source, you don't need to eat meat. My birds free range and help work the soil and keeps the bugs down. Even the old ladies do thier share of work and lay eggs well into thier twilight years. I have one chicken between 7-9yrs old. Not sure exactly because she was dumped in my yard a few years back and she was old then. Usually my chickens reach between 7-9 years of age before they die of age realted issues. Most of them lay remarkably well until they are 4 or 5 years old. After that it's more sporadic. I practice vaccination, routing wormings, and physical exams on a regular basis. The old one stopped laying last year. Up to that point she layed about 5 eggs a week. (Amazing production bird)
