Mine get into stuff they are not suppose to all the time. They are too curious. I have never had them eat insulation before though. I hope they are okay. If everyone is still okay friday and saturday, I would say it didn't really affect them. As that is plenty of time for them to try and digest it.So my stupid chickens, no I was not under the impression they were smart, decided to eat foam insulation while I was at work today. They pecked off a good portion from a place they have never looked twice at before. I actually did not realize they could get to it. I am really hoping they don't have issues because of it. They had plenty of food. Big dummies. Any one else ever had this happen?
