I think you are correct on #1 and #2. I think #3 may be a pullet, but would love to see a full side shot, because it appears the tail feathering may look more like the roo than the pullet. Any way to get shots of them together?
These are not great shots - the hooligans are flying all over the place and hard to keep contained when together!
Roo in the middle, pullet on the right, unknown on the left (unknown is the smallest of the three). The roo has a comb that is pinkening and wattles are starting. The other two still have pale combs and no wattles.
Side shot of the unknown
Another side shot of the unknown
The Charlie's Angels shot Roo in the back (see how pink his comb is getting?), pullet in the middle and unknown in the front.
Not great shots and I know signs point every which way, but I am super curious about what the experts think!
