I am asking this for a friend of mine, because he is no member of this forum and he is not able to write in English.
So, what happened: he got a pair of blue Orpingtons some time ago and the hen wanted to have some babies; she was so stubborn that he let her do whatever she wants, even this late in year.
But the problem came around the 16-17 day, and suddently she left her eggs. Weird hen, first she wanted babies and then she left them.
So I drove to him with my incubator and we placed her eggs.
Today he phoned me, telling me that two babies made it (3 are in the run), but he is a little concerned about how the black/blue one (he is not sure at the moment) look like, because it came out of the egg with a reddish looking comb around five hours ago.
The other one (the splash one) did not have a comb.
So, is it possible that the blue Orpingtons, the male ones, did already hatch with a comb? Or can this happen with females either, having combs from the start of their lives?
