Ok, we got a Hen and 7 new chicks, they're all in the run and coop. The brood hen does not allow the teenagers into the coop now. She is down right mean to them, they was in there for 12 hours last night, and everyone came out unscathed this am. This is unacceptable though, the teens can't get to the warmth of the light during the day or if theres trouble. How to remedy this, I guess is I'll have to build a new house or figure something else for the brood hen and chicks. Anyone else know of a different solution to this problem short of building a new coop? I do have an idea, we have an old hot tub that we used for a dog house for awhile with a "door" cut into it, I thought about using it as a temp house for the brooding hen till the chicks are older.
