So one of my BOs went broody a few days ago. I've been forcing her off the nest a couple of times a day and she will eat, drink and take a big poop but then heads back within about 10 minutes. She had managed to pull all the feathers out of her chest and will growl at anyone who approaches the nesting box. This is causing discord with my other three chickens, as they are now forced to share one nesting box and they don't care for it. We are rooster free and it is too late in the winter for me to want to get her some day old chicks to raise so I've decided to break her of it. I found a shopping cart down the street that someone had just left there, so I acquired it and put a makeshift roof of chickenwire over it to create what seemed like a good broody jail. She has been on lockdown since this morning, and I just wanted to make sure this looks like a good make-shift broody breaker, has enough room, etc. I did make sure the spacing on the floor was small enough that her feet dont stick through. See anything I should do or change? I'm planning on leaving her there over the weekend and seeing if she is cured on Monday.
