Careful with the boney parts, if you cook them at all they could splinter and choke him.
Pidge, you really need to wait him out. And NOT offer anything BUT the chicken. As hard as it is, this is what he needs. One day he wont eat anything, and then what will you do? You'll have tried everything and have nothing left.
It's our job as mommies and daddies to make sure our kids eat right. Whether they want to or not. Would you let your human child eat just icecream if that's what they wanted? No. You'd wait them out, eventually they WILL get hungry enough to eat what is being served.
Try offering just breat meat, NO CHEESE. Or whack a wing with a mallet to break the bones to make it easier to eat. The skin can often be off putting to newraw dogs as well, so perhaps offer a thigh after removing the skin?
YOU CAN DO THIS! We are all here for you, you just need to be more stubborn than him!!
