I have two 6.5 week old EE's that I hatched out, from diff hens eggs. One is all black(feathered in slow), and the other all sorts of colors. The black ones comb started turning red at like 2.5 weeks old so I assume a roo. The other one which looks to have some buff, red, black, grey all mixed in but is mainly a buff/cream color with some red and grey thrown in, and then a gold laced-black head/hackles. That ones comb is still the yellow/light pink color(this one feathered in extremely fast), I was assuming this one was a pullet due to fast feathering and the yellow/pink comb still at 6.5 weeks old. The black one started crowing last week, sounded hilarious, when we werent around them for a little while and then they heard one of us near the room where they are he would start crowing to alert his crew, Well now the cream/red/black one is doing it too, they go back and forth. Does that def mean they are both roo's? Or has anyone had one do this to try copying the other? They used to be able to hear my adult roo crow all day.
