I bought chicks from a local lady, she said these were pullets. I got them when they were a few days old. Now the Barred Rock?, s/he is about 8-9 weeks old. I'm almost positive that the black mix is a roo, not too sure about the white chick (not the silkie). HELP! Also throwing in a picture of my EE, Eggmerelda. She's, hmm, different or slow. Is she a she? She's always left behind, or running down the other chickens. She's 12wks THANKS!!
