I have a person wanting a male peachick to go with her hen also this year's hatch. Mine were hatched beginning of Aug. but not good at sexing them. One is a week younger than the other 2 but all are starting to green out on the neck. I remember someone saying that male bars are "blocky" Any ideas would be greatly appreciated. Here are the new pictures. I do not know which is of which but they are of all 3 of my hatchlings.
