Yeah.....not so much. Now the chicks are 9 weeks old, and their tails are telling me a very different story.
The little brown chicks, who had no tails or very small tails (one especially) at the time are turning out to have hen's tails, if you can see her in the back here. The white ones, who had tails at the time and should have been girls, are turning out to look like roosters. Do those look like sickle feathers to anyone else?
I'd almost place my bets on two roosters and two hens here, but I still have to wait. The one in the first picture, though, I'd 100% say rooster. The comb is red, the feathers are curved on top, and he usually is leading the pack. The other white looks like a rooster to me, too, but he's slower maturing.
Only time will tell. But I think we can cross this method off the list!
