This is a brand new venture for me. I will be a first time chicken owner sometime next week when my baby chicks arrive. I am So excited, it's just plain SilLLy! Thank you all for the great ideas here, helping me put together my first brooder! Since I have two large dogs and a frisky kitten facing their first encounter with me adding birds to our "pack," I thought better safe than sorry, and remodeled one of my previously used dog crates (RIP in my senior beauty, Miss Mattie Lynn). Except for buying a larger drill bit so I can mount the roosting poles at a proper height, I *think* we are ready to take delivery. Yeeee! I lined the back and sides of the crate with 1/4" x 2' x 4' wood panels, and the front side with plexiglass...So the resident critters and I can observe all that the chicks do and get comfortable with being calm watching them Just be Chickens I can still slide out the bottom tray for cleaning (and am pretty sure the kitten can not slide his paw through the gap), and I can access the chicks and the water bottles and feeders over the top of the wood panels through the back and side doors. I will probably add more water bottles, as I have three more chicken nipples at hand... Those are Ozarka sports bottles with CC Only chicken nipples screwed right into the sports cap. Anyway, all advice is welcome. Totally a newbie, and already appreciate this forum So Much!
