I posted one about our young pullets eating the styrofoam insulation from the walls of their new coop.
I was wondering if it were harmful. We took it out any way, just to be safe. I don't think it can really hurt your chick seriously, but maybe you could cover up the styrofoam walls with something like a cloth just to be safe??? I will see if I can find the thread.
Very cute chick, by the way!
