i just picked up this chick. i have many RIR pullets and have been trying to get a RIR roo for them but have been unsucsessful . this one is 5 WEEKS. comb is alot taller then any of the pullets ive had at this age. in the pictures,the long thin feathers growing on the head make the comb look short but the comb is much taller then the others at 5 weeks.
