I am anticipating/hoping for a broody hen come spring. I suspect if it happens it will be one of my dark brahma hens since a couple of them already have a 'tude about me taking their eggs. I have seen different size dog crates at Atwoods. One of the smaller ones seems like it would work great for keeping the hen seperate in that while she's brooding. I could tuck it under a shelf in the coop that's basically a no man's (no chicken's?) land. The shavings are never dirty or even disturbed under there, so it's pretty much an area the chickens don't venture into. Would the crate work there to keep the hen and chicks safe?
