I started with 20, lost one to at about 1 month, accident, the rest are growing great, 5 of the 20 turned out to be roo's 1 of which is mean to every chick in the pen, 3 are beautifully barred and the 5th one is dark,like a hen, i suspect he may be a Barred Hudson, the hens are kinda bossy also but not too bad, i also run RSL and BA with them, they constantly pick on those as they are a bit younger
