The organs and neck should be fine. Just watch him with the neck and make sure he doesn't swallow it whole. I feed my guys whole chickens cut up. Gunnar gets half a broiler (about 2-2.5lbs) and then the other 2 split the other half. The bigger pieces are better, they have to work on them more, rather than gulp down smaller pieces. I've seen our pug Bruzer swallow an entire chicken neck whole before, and the same goes for wings. He doesn't get them now unless they are attached to the chicken.
