Our five hens (14 wks old) were in their temporary pen outside today and an old child-size chair that we sometimes use to visit with them was left in with them for a few hours. We've done this before and except for some chicken poo on the chair, no harm no foul. Today though, when I went to check on them I saw that they had pecked and eaten some of the wood on the chair. I don't know how old the chair is or if it has lead paint. But my main concern now is how they will do with the wood they've eaten. The large strip across the seat of the chair is about 7-8" long and 1/4" deep in spots. Both front corners were pecked away as well but as this is an old chair and much of the corners had rotted away already. My daughter and I both feel sick -- we hope they'll be ok. Is there anything I can do for them now? Will they pass the wood? If not, how will I know? Would their crops get impacted? What should I look for? These girls are our first chickens and our pets. Their feeder was low but they were not out of food and they had fresh water. Their grit dish has grit in it. Their main ration is organic starter/grower but we give them treats from the garden -- grapes, lettuce, tomatoes and they had some today. They've been healthy girls and at this point -- an hour after I removed the chair -- they seem fine. I hope they'll be ok.
