I have two 5 week old bantam Ameraucanas and a Silkie bantam that I want to have out of the basement in the next 3 or 4 weeks. I have 4 other bantams (Ages 9 months and 4 months) outside in the coop. So, what can I do to get them to gain more fat stores and improve their winter feathering? I have had the heat off them for over a week now and the girl I bought them from said they are bigger than their siblings and more feathered out. I think she still keeps heat on hers. Right now they are on the Blue Seal medicated chick feed, they usually get daily treats of kale, ricotta cheese/cottage cheese, apples and pasta. I was thinking of giving them BOSS but aren't they a bit young for that?
