Our hens have 1/2 acre fenced where they free range each day. There are several goat houses and the coop. For several evenings our Mama hen would roost in one of the goat houses and I would have to move her and chicks each night into the coop. Last night she was back in the coop for the first time but with only one chick! I searched all over the field with a flashlight for the missing 3 chicks and couldn't find them. Finally decided to try one time with the Mama hen. I held her and walked with her clucking and finally heard the peeps I was hoping for coming from under the coop. The 3 chicks were all huddled together under some rolled fencing. Got everyone back into the safe coop and they all snuggled right under Mama hen. Today I am thinking we need to fence a small 10x10 area for Mama Hen and the chicks. We may put a door on one of the dog houses to use as a temporary coop for them... or I will continue to move them into their coop every night. Then we can use this smaller fenced area when our incubator chicks are ready to move down to the field.
