I have started setting up my brooder area on my enclosed porch, and i am using a baby yard as main support and cardboard lining the inside of it for drafts and also the gate holes are kinda big. I am using good ol duct tape to keep everything together. Now i am wondering if they will make it to the 6 weeks i had figured in this enclosure since "fort knox" it is not. The "walls" are about 2' high. How long will this keep adolescent chicks contained is my question? I just wonder if they will be moving outside before i am anticipating! Thanks!
