i saw ur other post with pics also and i thought they were both pullets at first. then saw there was an added color so i thought a pair. to be honest i think seeing them again it is 2 pullets and one is off color like it is a hatchery stock baby and at that age a roo should be a definate pink comb and dark in wings noticeable. ur's don't look how mine hatched boys and grew it looks different to me so i'm pretty sure it's a girl.
if u go on my site link in my siggy and go to the mixed pen i have i have pics of a pair on their that r purebred bantams a little older than urs. couse they look totally different now since older and have adult looks but due to winter i don't have updated pics but mabe it will help to see what u should be seeing soon to know for sure. i don't know if i have any younger pics will have to check my comp. usually they hide from the cam though,lol.
hope mabe that helps ya some,
