I had the chicks outside in the pen today since it's such a nice day. They were out there for a good four hours with no problem. I was sitting outside and noticed a chick somehow got out of the pen. I went to chase it and it spooked and ran into some underbrush/shrubs in my neighbor's yard. My husband, son, and I all looked and we could not find this chick anywhere. After an hour of looking we had to give up. I'm sitting in the porch hoping it will peak out or something. I feel so awful.
