Here are my 5 EEs. They are 7.5 weeks old. I'm pretty sure the first one is a hen and the last one is definitely a rooster since he started crowing yesterday, but I'm not sure about the 3 in the middle.
#2 could go either way, but it does look like most of my late-blooming cockerels rather than a definite pullet. The last one is a definite cockerel and the rest look like pullets. Cute birds!
Chick 2 has a heavier body than the others (except for the rooster). It doesn't show so much in the photos, but he/she is a lot stockier than the other 3. My gut instinct says it's going to be a rooster, but I'm really really hoping it's not.
