I'm not really sure......

They are now 10 wks old. Chick 1 started crowing about 3 weeks ago. Chick 2 and 3's crests are very rounded and I'm confident they're pullets. Chick 4 is harder to crest sex as they are frizzled, whoever there's no real redness in comb or waddle and still no crowing so I would say I'm about 80% sure it's a pullet too.
