Her chicks are 4 1/2 weeks old. They are almost fully feathered - still some downy patches here and there. I am hearing some squawks from the chicks and it seems that Calypso is starting to distance herself a little. I am wanting to get Calypso back in with her old crew and am hoping to do that this weekend or early next week. Is it too soon? They are outside but are relatively sheltered and I also have a heat lamp on when it is cold and usually at night. I have an extended nesting box/ broody box that is loaded with wood shavings where they spend the night. What are you opinions?
