I feel for ya. I've got two EE "pullets" that are about six-seven weeks. One has already been crowing for two weeks, and I found a beetle-green tail feather on the other one yesterday...her overall coloring looks more like a hen but I'm worried now.
Ditto here. My 10 week old Welsummer, McGee, crowed twice today when I was in the coop.
I had heard something previously and I thought it might be the Easter Egger. But if he is a rooster, he is keeping a low profile. I'm pretty sure the other 7 are ladies and I had gotten a couple extra in case I had roosters as I don't want to do the chick raising thing very often.
McGee will be going to a "chicken farm" in the boonies on Sunday courtesy of the place where I bought him (Urban Farm Store in Portland). They said, very convincingly, that he will live out his natural life there and will not be eaten. Not much I can do about it any way since I'm not pissing off my neighbors and keeping a rooster. My other neighbor has one and, while I don't mind, the last thing I want is to attract attention of code enforcement since I'm a tad bit over the allowed limit - ok, 3x the limit.
