i just read that on someone elses post, that an EE with a pea comb with three distinct grooves is a roo for sure. My betsy was the LAST one i would have thought was a roo. At first i thought she might be dominant since she would stand in the food and peep at the other girls, but she grew so much slower so i thought she couldnt possibly be a roo. I have had them all for three and a half weeks now and my other EE girl is a bit bigger but barely any comb and its defiantly not red. Betsys got redder and has the defined things in it... is that a for sure thing? Here are pics, sorry not great because i only had the iPad to take them with. my camera has a dead battery!
