Hello, My little chicks got out of the yard today. Luckily, my neighbor saw them and penned them up until I got home. She put in the pen a saucer of cracked corn though and I don't know if that could cause problems. So far they've been on the Medicated Chick Crumble only. Do I need to provide them something in case they ate some of it? Thank you for your help. p.s. I fixed the hole so they can't get out again, too!
