Give them time. But is it chilly enough that they need all their feathers? The advice to wait till they are fully feathered out is because it's often chilly and they need the feathers to stay warm. If it's as warm there as it is here, he'll be fine outside.So, I know, or I've read, the male buffs feather out slower, but my chicks will be 6 weeks old Monday, my female BO and my female SS are fully feathered. I want to put them outside, but he's still not feathered out. When do they get fully feathered???
