Pardon my odd question...
I have heard that with EEs leg color indicates egg color? Green legs for green layers, and slate legs for blue? Is this just an old wife's tale? And how soon can you identify leg coloring in young chicks?
There is no link to the egg / leg color. The only visual trait that has been "linked" to the egg color is a pea comb vs non pea comb. The pea's will have much higher percentage of colored egg laying (either form of green or blue depending on the genetics of the parentage) but that is not 100%
