This is our second broody. The first I moved into the garage so she had peace and quiet and let her raise her chicks in there until they were a month old then moved them back into the hen house. It worked fine although only 3 of the 7 are still with us and 2 are boys but that's another story. I'm thinking with this new one I'll leave her in the nesting box in the hen house is this a bad idea? They make a hell of a mess in the garage. There are plenty of other boxes for the non broodies. My only concern at this point is the boxes are rather high off the ground about 2.5 feet. Is that too high for baby chicks? It's also much colder now with our first frost last night is that a concern?
