I have four chickens about 9 weeks old that I bought as chicks, 2 rirs pullets, one barred rock cockerel and one slw cockerel. I wanted more layers, so this past weekend I bought two rir pullets and a cockerel from another person than the first 4. These birds are in great shape, as healthy in appearance as I could ask for, good feces and all. The only thing that I noticed is that my original 4 have pretty dark yellow legs. The three new RIRs have almost stark white legs. Is that something to be concerned about? Ive heard that hens legs turn whiter the older they get and the more eggs they lay. Is this some sort of mineral difficiency that I need to be concerned about? Also...anybody in the area looking for a Barred rock or SLW Roo?
