I have 6 girls. 2 Sexlinks, 2 Americaunas and 2 Buff Orphingtons. The girls have a 14 x 14 indoor area with supplemental lighting, and they free range at will (which is dawn to dusk). They get good food and plenty of water. They are less than a year old, all hatched within 2 weeks of each other. First my Amercaunas stopped laying and started to loose LOTS of feathers around the head, neck and tail. Now they have pin feathers coming in. Then my Orphingtons were loosing feathers and stopped laying. Now they are looking better, and I don't have near as many feathers loose in the coop. None of these four a laying. My black and red Sexlinks are faithful champs and give me an egg a day, and have lost no feathers. Aren't my girls too young to molt? I'm not so worried about them not laying, I'm chocking it up to winter (single digit temps). Maybe I'm wrong to not worry??? Any thoughts on this would be greatly appreciated, we are first time chicken owners. I did go pick each up today and they all seem very healthy!
