I'm pretty sure at least 2 of these are roosters but I'm starting to think that all but 1 may be roosters. It's so hard to figure out a few of them. The big barred rock was born the 1st week in June. The other 4 were born on the 4th of July. The smaller barred chicken is suppose to be an easter egger???? I'm a first time chicken owner and I am totally confused. Please help. Thank you for your time.
