I don't let them out of the coop and runs as of yet. They will be 3 months old this weekend. This morning there was some snow in the upper run so I only let them in the lower one which I had covered from the wind. It was 23 this morning and hasn't gotten above 26 so far today. Going down to 13 tonight. They seem to be handling the cold very well.I would love snow if I only had to tolerate a dusting here and there. How did the chickens like it?
