I dont know how to break them or even if it's possible!! I have 2 broodies. One is healthy my other is a sad case indeed! I remove them from the boxes countless times per day. I have put both in wire bottom cages for days on end. I put them on the roosts each evening! As I stated above, one has become quite thin! I give her extra treats and put her in front of the feeder each time I remove her from the box. She eats a little and takes a few sips of water. Then she's back to the box! Their broodiness has continued for 2 months!! The vet told me that it's hormonal and to simple continue to do what I am and they will stop after a few weeks....they wont stop!! HELP!!
