I am thinking Roo, but the saddle feathers are looking rounder than my other Orp Roos and the neck feathers are also more rounded than his (cuckoo Lav). The comb/wattles are really red.
BUT I introduced three new hens to the flock and they are beating the mottled up quite badly, which I wouldn't think should happen if it is a he? Today it also squatted down when I went to pet it. 11/12 weeks old.
