Eva has been trying to help me understand wing sexing. See Eva's wing sexing entry. She has emailed me several videos on the matter and tries to explain it to me, though my brain doesn't seem to necessarily be taking in this concept. The premise is that on days one through three of a chicken's life, we can tell the gender based on wing development. The girls have two rows of primary feathers, and the boys only one. If i'm doing this right, i've noticed that the boys also tend to have fewer visible primary feathers.
I happen to have eight new babies at my house, who started hatching on Friday - and who were all hatched by Saturday mid-morning. So today is day two of life for most of them, possibly day one and a half for some.
I'm not sure i know what i'm talking about here, but i'm giving it a shot and hoping for feedback. Here we go....
This is a nice place to start because i know that this one is a girl. She's a black sex link, and this is her wing. She was one of the first to hatch, so this is definitely day two for her.
This one might just be younger than the others, but since this is at least day one and a half, and there is hardly any visible feather development, i'm going to call this one a boy also.
This one throws me off a little because i CAN see some slight development of a second row of primary feathers - or at least i think i can - but i think this is a boy because there are way fewer primary feathers visible.
Female. Eva says the girls' feathers also look a little more tapered, like they've been to the salon.
So i see four boys and four girls. What do you think? That's exactly what i got when my dog had puppies, four boys and four girls, but they were easier to sex.
