I have 4 13 week old Colombian Wyandotte Bantams. Two have red combs and waddles and are showing iridescent blue/green in the tail feathers. They are not showing hackle or saddle feathers that are different from what I am pretty sure are girls. In fact one of them has pretty rounded neck feathers and the other one has neck feathers that look just like the ones that have no comb or waddle. Had a BLG that looked like a boy earlier in the year and now she lays eggs, so I am a bit nervous about Wyandottes. Does anyone have experience with these chickens and if you can be sure before they crow or lay an egg? Will try to get pics this weekend.
