So, the 1st one is the suspect D'uccle? Yes it has a lot of comb...but the cochins, esp the last one, are less developed....
I'm glad to see them out on soil/grass to help develop resistance to cocci. Everyone healthy?
When you are completely sure he's a male, I'd be interested in taking a trip up your way.
I have 9 chickens, 3 are hens and 6 are pullets almost 4 months. Only 2 pullets are bantams. I had included them in my order of Leghorns hoping to get a little rooster, but they are both girls, a Sebright, and a MF d'uccle. I had wondered how the size difference would work out, there's no problem. The bantams are treated as equals..by hens and pullets alike. I imagine that a younger cockerel would be shown how to fit in, after an introductory phase in separated quarters where they can see but not touch. The others all integrated seamlessly that way.
Here's a pic of the 2 bantams w 2 of the br. leghorns. The 9 girls have about a 1,000 sq. ft. run, and a walk in coop that is about 45 sq. ft. It's a nice little habitat. I think we have room for a rooster.
