I have two chickens who never leave each other's side. They are free roaming chickens but at night they get locked up inside. When the sun starts to go down they usually go to the coop themselves. Tonight I went to lock them up and only one chicken was in there. My other one has not been found and she has been missing for 4 hours!!! What do I do??? I've looked everywhere! Trees, under sheds, houses, and porches, in the cornfield! I have tried bringing out her favorite food but that hasn't seemed to help! What do I do!?!?
