mayla, i don't think you could eat your chicken pet. after all , you'd have named him/her. that's the first step that you cannot do when you plan on eating them. who wants to say to their guests, we are having 'henrietta' for dinner.
i'd say the same for sheep and goats. of which you may not have in mind. my mom had chickens, ducks, sheep, goats, one horse, a turkey, etc. and they all became MY pets. she never named them, but i did. it was a heartless thing to butcher them, imo. (not the horse). they thought they were important (especially to me) and i treated them as people. i couldn't eat any of them, and much preferred the store bought meat. they had personalities to me. they were real live personalities and didn't do anything to deserve death.
no,m1469- just have them as pets and feed them and take care of them and they will be good to you, too. i still remember my duck (what's his name?). that's all i have to say. (forgets that rhode island red rooster that almost killed me with flapping wings).
ps just in case you don't understand what i meant about butchering and horses, we did not butcher the horse (he was probably the only one that started acting all funny as he got older, though).
