I do not. However, it is for an entirely different reason: I do not buy store chicken. All of the chicken I eat are mine ('extra' roosters and older hens) I feel it would be wrong to feed them their friends. Besides, I eat all of what I make/cook, even making broth and/or chicken soup with the remains...so there would be little if anything nutritious left. Plus, cooked chicken bones is a bad combination with a dog. He (Elroy) does peruse the chicken run on occasion - especially in the evening - we put him on rat duty! And, he is good around the chickens - though it is still only when we are out and around that he gets to be in the chicken run!
That said, I think no less of you for doing so - nor should you think less of yourself. You and
@BY Bob can choose to do what you feel is right (just as I do for myself), and no one should judge, since neither of you are neglecting nor harming your feathered friends. So, the real question is: can you live with what you have done? If so, fine - drop it. If not, okay, don't beat yourself up - what is done is done, so, drop it!
(See: all is okay! Let it pass from your mind either way!)
