We really need better close-ups of each bird in question. Get a side shot of the head and a full-body shot from the side also. Get them as "close-up" as you can so we can better see comb growth, hackle feathers, etc.
And by the way, that's awfully tight quarters you have them in right now. I see that they have feathered out...any particular reason you still have them in that cardboard box?
