I adopted 4 EE's a few days ago. I was told they were all female, but not knowing much about EE's or pea combs (my other chickens are all heavy breeds), I didn't second guess the gender if them until I got home with them. I do not know how old they are... They appear young though and I'm uncertain if I see just a chunky rose comb or 3 rows indicating a roo? Help!
