I have 2 pullets, a Wyandotte and a Buff Orpington , that are approx. 40 weeks old. They are steadily providing me with 1 to 2 eggs a day. They are in a coop with run enclosed in a 10' by 17' area. Inside this is a smaller run area (enclosed) containing an English Game Bantam - age unknown. He was given to me about the same time I got the girls and I am assuming him to be grown. The rooster's coop & run share a hardware cloth side with the girls, so they have always been in view of each other but without any physical contact. Our temps have been dropping into the 20's and the rooster has developed some frostbite on his comb. I treated it with Neosporin which seems to be helping. My question is - Would it help to allow him to be in with the girls? I wonder if they would all huddle together at night and the girls feathers would help to keep him warm? And of course I wonder if their finally being together would create any problems.
