I use quails and chicks as an even part of my boas and retic diet now that I got a supplier for them. Caesar and Vicky go bonkers when they smell them. Rosey not so much, she still likes her rabbits more. I'll also add in rabbits to Caesar and Vicky's rotation when they get big enough. And eventually, i'll do gpigs for Caesar too.
Now mind you, these are whole prey with feathers and everything, not a chicken leg or gutted, plucked chicken from the market. Not too sure how good those would be as half the diet for a snake.
