I've been watching their behavior, my little ladies are fully feathered out, I got them Oct 22nd, little Penguin of the crooked beak is growing ok. They still huddle together on the floor of the mini-coop at night, rather than perching. (unless they are cold then they all perch under the heat lamp - but it isn't on unless temps are below 45.) However, I saw Hannah fly down off the greenhouse shelf this morning. I've got the windows cracked so they are ventilated but can't get loose, critical when my dogs are out. So, I can clean up the big coop and add some half steps going up into it - they are 12 inch spaced right now. But when are these pullets moving out with the hens? They are still on chick feed. The hens are on layer and game bird layer feed.
