Still no sign of him, so he's either *gone*, or happy wherever he ended up. His litter mate, my only rooster now, seems somewhat lost without him. They were always close, like actually touching when they'd do dust baths and stuff like that, but the hens don't allow such things and sometimes he's feeding by himself fifty yards or so away from them. He also goes to roost first, sometimes a half hour before the hens. Today he was on the roost while the hens were still out of sight somewhere behind the house.
I don't know if I should be looking for an older, more experienced rooster, or give up having a rooster. I like having one, but really expected him to play the role. I'm also still in the learning process, so I'll keep cruising the threads here and see what else I can learn.
