Hi all! I have successfully hatched a brood of quail. They are five weeks old and all seem to be doing well save one. He is my runt that had to have help getting out of his shell. He overall is doing great but he is half the size of my others. This week I took them out of the brooder and placed them in a coop with a run. We are in Montana so safe to say it’s getting cold. It was about 45 degrees outside when I placed them out. By evening as I went to move them all into the coop, little Mumble was snuggled up underneath one of the others. I moved them all into the coop and came back around to check food and water inside the coop. Mumble was flat out on his stomach and clearly was on the verge of freezing to death. I was able to get him warm inside and back into the brooder. While warming him I realized while he has all of his main feathers he has absolutely no down. Any ideas on why he hasn’t feathered out completely like the rest and how can I help him develop enough to rejoin his group??! Thank you for any suggestions you may have!
