Your post is great! You've restored my peace of mind, having some of your MIA's return. My DH will be glad to hear of your chick's return, since one of mine has gone missing. Thanks for your update!
Escapees! Keep your remaining chicks on the daily routines, out in the run. You might see those two MIA's trying to get into your run.Hope you can catch those little rascals, and put them back with your flock.
