Hi, I guess it is about time I join BYC since I've been reading so much good info here and felt like a stalker. My chicks will be 8 weeks old on Monday. I started out with 21 (3 were freebies from the hatchery) day old chicks (ordered as females) that I picked up at a local hatchery and all survived infancy. I sadly culled one really aggressive, obvious rooster at 4 weeks. :-( Since then I have discovered I have at least one other rooster in the gang and I'm suspicious about at least one other one. I guess the sexing by the hatchery is still in the acceptable error rate of 90-95% but I'm getting a bit nervous as I watch the remaining chicks develop. The good news is that there are no additional aggression issues...yet. I may soon be posting some pics in the thread about identifying sexes.
