Hi, first timer here. Please help me identify the gender of my 9 week old chickens. Also, what breed is the chicken in the last photo? He/she was sold to me as a GLW. Thanks!

Welcome to BYC!!!!

Looks like you have a bunch of lovely ladies there! The last one could be a welsummer pullet. If she starts laying speckled or really dark (terra cotta) eggs then you'll know for sure.

Welsummer pullet? Thanks, I think you may be right. The feed store was selling those at the same time; maybe a couple chicks got mixed up. And all girls?!!!! I bought more than I can keep because the Polish were straight run. Now what? Build a bigger coop? The first one isn't even finished! LOL I'm loving this new little adventure into chicken keeping! Thanks for responding.
