Being very new to the world of chickens I have a few questions about breeding ethics. I know very little about chickens and breeding but I know a lot about dogs...and the ethical concerns with mixing breeds, marketing hybrids and breeding substandard animals without proper testing and conformity to health standards. Obviously these are two very different animals with very different functions. I wonder about the ethical concerns when breeding chickens...What are the implications of producing and buying hybrids? I notice there are breeds on the conservation list which makes me wonder if the production of non-breeds are stamping out many of the heritage breeds for their faster production. Do roosters get culled in experimental breeding because of the difficulty with placement? If so, how is this justified? I notice there is a great deal of experimental breeding with chickens...Are there any newer breeds that are awaiting validation (by breeds, I mean unrecognized breeds that are able to breed true.) Lastly, how does one determine good breeding stock? In the dog world, I look for a strong pedigree, attempts by the owner to compare his or her stock with others (shows, competitions)... Also...do chicken breeders follow the idea that form follows function? Sorry for all the questions...I've been wanting to understand how chicken breeders operate and how the ethics compare with breeding other animals.
