Bein' farm-raised tends gives me a different perspective than most, in regard to distinguishing between pet and product ...
We buried our milk cow upon her favorite hill, next to the tree she'd torment just prior to chasin' everyone away from our barnlot ball games. But, we often sold others we'd named. Don't believe any of us named anything we planned eat.
It's not an absolute, in that the lines often blur. I'm fortunate, in that this farm requires protection from taxation far more than any need for profitability (can't imagine many here could justify keepin' chickens by arguing economics). I do try to guard my heart by stickin' to my more reasonable perceptions that my chickens and guineas are to serve this farm's need for documentation of productivity, but there's a few of 'em that just keep peckin' right through this armor of logic I cling to ... tryin' my best not to even have fovorites, but I'm failin' terribly. However, I've still not given any of 'em names.
And, in determining which one's which, you might start by asking folks their chicken's name ... if they've got an answer? It's most probably a pet ~'-)
