That is exactly what I did last night! UGH!! Our chickens are normally in a run. Sometimes I let them out to free range all day. Well, last night when I was shutting the run there was one lonely chicken. I have no idea how she got out. I got her and put her back in... This morning I hear a lot of talking like there's a chicken right outside my window. Sure enough, there was! She must have been with the other one. Aye..aye..aye.. guess I need to start counting when I tuck them in at night! Luckily no one found her for a meal!
