I have 8 pullets and 6 of them are going nuts for the insulation of the bottom of the coop. It’s just plain styrofoam, but I’m worried if this will harm them. I try to stop them, pushing them away from it when they try to eat it, but they’re sneaky and do it while I fill the waterer or the feeder. I really hope this won’t kill them. They can only eat it when the door’s open though, so it’s not like they have 24/7 access to it. Is this normal? HARMFUL? And can I stop it?
