I think a drumstick might be way too big for the little guy. It tastes fantastic and he does not want to give it up, hence the growling. I would try wings for him cut in half. He should be able to bite through them.
I think you are right. I was even thinking “drumettes” which are just the large wing bone, with the small wing bone and tip cut off.
He’s still growling, not eating. Odd.
Okay, I just cut off a chunk of meat. He gobbled it down. Now he is chewing and growling. I think we may be okay. :)
