Flower, I just saw the pics of my babies.... they are bigger already. D'uccles love to fly around. I have caught them trying to roost on branches 6 to 8 feet up. When I let mine out to free range, they fly and hop around. It's so cute! I actually had your babies under a regular 100 watt bulb suspended from a heat lamp for a couple of days before you got them. I use a red brooder bulb when they are really little, it gets really toasty and keeps them from picking each other.
