"None are better." I have no idea what that means. "Better" for whom? The people who practice inbreeding? The people who don't practice inbreeding?
No, I'm not going to "calm down," nor am I going to "f*ck my mother," as you recommended. I have long been active in animal rights, and that includes the rights of animals in "hobby farms" where animals are inbreed and the offspring die.
Commercial farms are regulated - even in Canada - by the Department of Agriculture.
If the death rate - so far two donkeys out of two donkeys have died as well as a rabbit or two - on your "hobby farm" were to happen on a commercial farm, you would be investigated.
Depending on which animals are being bred, there are regulations regarding in-breeding which is a very common practice on your "hobby farm," a practice with which you have no problem.
"Better" for whom? The animals on "hobby farms" which may not be treated well. The animals on commercial farms which may not be treated well?
Difficult to say.
EDIT: Commercial farms are REQUIRED to have Veterinary care available for the animals. "Hobby farms" - particularly yours - apparently don't bother with Veterinarians (despite the deaths of inbred animals). Your parents have a good laugh over the situation?
“We ve been on our farm for 14 years now and NOT one animal was deformed or unhealthy. They do not have health problems ... The only times we ve gotten a vet to come over is when our one origianl sheep (not inbred) had a baby and couldn t walk. ... I find it kinda funny and disturbing even my parents have a good laugh with me about”
