anything else?

i was wondering if you could feed a ball python or a red tail boa chicks. would it work?

Sure you can feed them almost anything. But the question is will they eat it. Unless you live on a farm and have an unlimited supply of chicks, they are going to cost you more. Also, I don't think the fat content will be anywhere near what a mouse or rat will have.

Could also be more difficult for the snake to digest the feet and beak of the chick.

All in all, I would say it's not worth the effort.
