They are fast and I have tried to hold them both but then I don't have a hand left to take the picture. You can see the size difference. The little one hasn't changed since about 2-3 week. No new feathers. It cheaps a lot just like my silkie that is extra small. It's always trying to get under the others to stay warm. I don't have anyone else her size to seperate her. I don't want her alone.Is it possible for you to get some better pics of them close up?
