1 serama rooster
1 old English game bantam
1 buff Orpington
2 Rhode Island reds
It's winter and my chickens are spending all their time in the coop, being confined so closely the Reds began attacking my bantam, so I set her up a shelf in the top of the coop with her own nesting box food and water just to make sure she has a safe spot and is getting food and water. I noticed she was staying up in her loft more than usual and thought the Reds were just getting more aggressive. Finally I wrestled her out of her nesting box fearing she was sick or Injured to find her on 8 fertilized eggs! If I would of know she was broody I would of tried to break her but now it seems I have chicks on the way. I'm at a loss of what to do as its winter and gets well below freezing where I live. I know I have to move her out of the coop, she will not be able to protect her chicks from the other hens.
Advice on how to go about moving her and what to do when the chicks hatch?
Should I build a makeshift coop for just mom and chicks?
Should I make a brooder and bring them inside?
Should I just remove the two reds?
