We have a bantam hen (Big Mama is her name) that got pretty beat up with our other flock. I pulled her and put her in a rubbermaid container in the garage and it seems she will be there until spring. I am surprised she survived the first night. Every time I try to put her back with the flock she is shunned and chased. The problem is she is pooping everywhere and our garage is our kids play area and my workout space. What kind of container should I get to keep her in for the next few months? We are really attached to Big Mama.
