I have a pair of what I think is BBB. I really wanted to just let them hang around, but it's becoming aparent they're going to flop over dead due to be fat. What I'm wondering is if they are too old to butcher. They are about ten months old. I'ld put the tom at about 30 or 40 pounds....Also is it common for toms to "pant". He always seems to be out of breath wich is the reason for the delayed thanksgiving.
