Lavenders are hard to tell, I almost sold a couple of my LO off because I thought they were roos, but one LO hen was just very petite. 12 weeks is a long way off before they will lay eggs anyway, I would just wait and see. I tried to get girls, but I thought LO's are so popular, I would get my money back from the chick even if it ended up being a boy.
To me that looks like a hen.
My hens are 6 and 5 months old no eggs yet. My older hen is molting so no eggs from her... My mutt rooster is working so maybe they will start laying soon.
