This one is from the same purchase and completely different ! So odd. I wouldn't think the feed sore would mess up with 2 out of the 3. Could they just be developing faster?
Hmmm, the first two look life roo's, sorry, but the last one looks like a pullet. Bit there is always a possibility of all of them being pullets, but a low chance.
From what I've read on here, bright red before 10 weeks means roo. I bought 6 hens (3 barred rock 3 buff) which were all suppose to be pullets. All three of the buff turned out to be roosters. Maybe it's a buff thing? I wonder if they are harder to sex.
