We do not have a broody right now but we finally have fertile eggs. We live in West Texas and we usually get our first freeze around Halloween. (Hatching time if we started incubating now) In the past we have kicked them out of the house pretty young, and we have NEVER had one die from this. If we had a broody I would not be worried, but at what age would we be able to "harden" them off and get them out of the house/garage/barn. Our area is known for winters with 70-80 degree highs in winter and an occasional freeze every month at night. Any tips or suggestions are greatly appreciated!
