They are adorable! What colors will they be when they mature?
The Red Star should be a lovely coppery red head and cape feathering, fading to a white/tan on the body and underside neat the vent. They lay brown eggs and are known to be friendly "pet" type chickens if handled alot as youngsters.
The Golden Buff (sometimes called Golden Comet) will be an all over light gold/tan color, and also lay brown eggs. They are a "bulkier" type hen, and known to be easy going and not so noisy/fussy. I have read and seen many different coloration's on these hens, so who knows just what we will get when they grow up, so have lacing and some don't.
