whew! Good to see that other's 'exactly like OP' chick turned out to be females. I have read a lot of posts that indicate that the light chipmunk EEs tend to be males. There is a thread here somewhere, where someone collects pics of ee chicks, before and after. I haven't been able to find it again, I think it was a few years old?
Well, turtle, my 2 week old chicky looks exactly like yours and I have no idea what to expect! I guess that is part of the fun!
