Our young pullets keep eating the Styrofoam that is lined around their coop walls!!! I don't know why they like it, but for safety reasons, we took it out. They have been snacking on it quite a lot before we took it out, so will this affect them at all??? I hope not! They seem fine now, almost ready to lay some eggs! But I am wondering if after eating that stuff they will be affected. Silly girls!
