I have 6 chicks. 3 are red sexlinks, so no worries there... but my other 3 are RIR. One of them has always been further ahead of the others, I thought maybe that was just the way she is... like people. But I am getting nervous that "Rose" is a rooster because her comb is larger and more pink than the others. Chrysanthemum is sort of in the middle, and Violet I do think is a girl. I got them on mothers day 5/9, and was told they were 4-5 days old.. so, they are about 5 weeks old right now. Here are all 3 together: Rose- is she a he?!? (though pics make her comb look more red than usual): Chrysanthemum (hmm, middle, not sure): Violet (think is hen): Yes, they all have flower names... my red sex links are Daisy, Lily, and Buttercup EDIT: Thought I would update in case anyone came across this post in a search. I gave away "Rose" and Chrysanthemum" who were almost definitely boys. However, VIOLET is here- she is a laying HEN.
