I’ve taken photos at 3 and 5 weeks so far of my 7 chicks — New Hampshire Red, Easter Egger, Barnevelder, Olive Egger, Chocolate Orpington and 2 Isbars. All from Mount Healthy. All hatchery sexed as pullets. My guess at 5 weeks is anywhere from 1-3 cockerels, but I’ll be curious to see how close I am. I’ll post pics of successive weeks. Sorry about the 3-week photos… they were taken while on their first trip outside on an unusually warm Colorado day. We’ve had chickens for 15 years, but haven’t had babies in the brooder in a long time, so the guessing has been fun. Personality-wise, EE and New Hamp, friendly and sweet. Isbars very active. Isbar #1 and Orpington always chest bumping. Barnevelder and OE least friendly. Did not get a good photo of the OE at 3 weeks. Isbar 1, Choc Orp and Barnevelder slow to feather and still downy spots on wing bows at 6 weeks. I’ll post pics in separate threads.
