I have 2 snakes an Albino Corn, and a BP.

I do not feed them in their enclosures for obvious reasons. They also have their own feeding cages with a hide box in each one. i have noticed that if I put my Corn's hide box in my BP's feeding box he will stick his head in it and come right back out, because he is not use to the Corn's smell. So, I would say use a different feeding boxes for each snake, because they are extremly sensitve to each other's smell.
