New to raising chickens

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.

 

Thanks! Not too far away...I'm in Missouri!

 

Thanks for that note about roos! I'm hoping to keep all if they continue to stay within acceptable behaviors. I actually would want good behavior from the hens too! Ha! Luckily, I am not in an area that prohibits Roosters so it will be interesting to keep all remaining. As soon as I figure out the photo uploading, I'll post some.
