Our girls are about 20 weeks old. They are laying quite a bit though there are still some soft eggs and the eggs are still small. This is a group of 5. No rooster. They are in their run at night or when we are going to be out for several hours (lots of predators around). They free range when we're home. One of the chickens frequently breaks off from the group, and goes off on her own. We'll see 4 of them in the woods scratching around, and the other (always the same one) in a different part of the yard doing her own thing. She also comes up to the door a lot which seems to be for human contact (she loves my daughter, who has handled and cuddled them a lot). At one point we found her in the woods sitting on three eggs, but other than that she doesn't seem especially broody. When they're in their run/coop, she "fits in" better. She's just......different than the others. Does this sound like normal variability in chicken personality? Is it anything to worry about? Obviously when she's off by herself she is more vulnerable. Will they at any point reject her because she's not 'getting with the program?' She really seems to have a different agenda than the others. Ironically, my daughter named her "Adventure Chick" when we first got all of them. It is turning out to be an appropriate name!
