well its win win for me either way then !Some of the hens just have big waddles. And see how the black in the roosters' tail feathers have a green oily sheen to them? If she has black in her tail and it doesn't have that, you're 99% safe.
My girlfriend and I both work from home, and we spent the majority of last spring/summer raising 29 babies and predicting the genders. If we are wrong, we will ship you a dozen eggs. You have a hen :]
We should know very soon, She (& the blue based cockerel) hatched late Oct2013, all the girls in that grow out group are w/in 3 wks in age and most are reddening up this week and the nest box has had the staw wallowed out and moved around every day, none of the boys have crowed yet but again I think we are days away from eggs/crowing. Which is why I'm so pleased we got a break in the weather this week. I'm cleaning pens and moving birds for pure breedings asap. I should have a flock of SFH chicks growing out this spring which will be fantastic.
Were your 29 all SFH? If so did you get _all_ the colors? That is my goal, a SFH flock w/ _ALL_ the colors, I figure that might take several years.
