I have some the same age as yours and same looking breed and some have red combs already and little red wattles and some are still flesh colored. The red ones are much bigger I will take some pics and post them for you to campare. But I see pullets compared to my birds.
Right on!!! Post em up realtreegirl! I'm interesting in seeing more chicks like mine they were at a feed store and sold to me as Rhode Island Reds and Black Sex Linked. We bough 5 rir and 3 sex linked. 1 sex linked died so replaced it with 2 amaracans and a silver lace Wyandotte but they are a couple weeks younger so didn't even post pics of them. My kids took the pics so really can't tell the difference between the brown rirs from the pics and just posted some of the better looking pics
