I cant see why you cant..i feed most of mine necks all the time to give a little variety..my BHP and the carpets love them....Ive given them necks for years and IMO they are good for them...seem to put good condition on the adults...
My understanding is that pythons still need rats.
Chicken necks should only be fed occasionally, and that rats provide valuable nutrients, fur etc that chicken necks do not give.
I'm sure someone will be quick to tell me if I am incorrect
I would only use chicken necks and drumsticks sparingly, if at all. Pythons need whole prey with all the skin, fur, guts and skeleton of the animal. Chicken necks are just bone, some meat and fat.
One thing I don't like about drumsticks is that the thick bone can sometimes be hard to digest even when they are kept at optimal temperatures.
I'd be more inclined to give diamonds in particular less chicken necks/drumsticks then what I usually would. I am of the opinion that diamonds are rather fragile and should be kept in optimal conditions. Other wise go for it. All my snakes have been given chicken necks for almost eight years with no ill effects.
