Can anyone tell me if the wing sexing method works on all breeds? I had 8 chickie babies hatch out today and now that they have dried I can look at their wings and see that some have only one row of feathers, while others have 2 distinct rows. Since I can only keep a couple of these babies for my gardens I want to make sure to get girls. Thanks. PS. If this is in the wrong forum, I apologize. I wasn't really sure where to put it.
