Is pearlite dangerous for chickens?You are so aware of your flocks health, I’m sure she will be doing better in no time. You will keep us all updated, yes? Sometimes I find someone will just have an off day. Hopefully that is all it is
And as an aside, if you have any styrofoam in your yard anywhere, of any sort, remove it. They love to eat it, and pearlite! From potted plants... I swear they will get into everything, but they LOVE styrofoam. Coolers, rigid pink insulation boards, packing from appliances...
