Chickens will eat the strangest stuff! I let mine out for a while today in a new area, and noticed a little piece of insulation on the ground and they were picking at it. Then I remembered I had poked some in a crack in the foundation of the shed last fall to stop drafts from getting in. I saw where they had pulled at it, so I poked it back in real far, and stuck a stick in the crack to cover it. The next thing you know, one of my Delaware hens is running around with this pink gob of "pseudo cotton candy " in her mouth. I pick her up to take it out of her mouth, and it was a big piece, half way down her throat! I'm surprised she could even breath! Well, I have been worried about giving them hay because of the crop issues, but I didn't expect this! I don't think she actually swallowed any but I guess a little woundn't kill her if she did. Should I be worried?
