I have 5 chickens, 1 leghorn and 4 rhode island reds. The leghorn is definitely a hen as she just started laying white eggs. I know I have at least one rooster from all the crowing that's been going on. I'm afraid though that 3 out of 4 of my RIRs are roosters....I have chickens for the eggs not the crowing. I've attached some pictures that aren't too good but the best I could get. I think the last RIR pictured is a hen, but I can't be sure about the others. Even when I look online at pictures of RIR hens v. roosters, I can barely tell the difference. Can anyone offer any tips on how to tell? I bought the RIRs when they were pullets, about 8 weeks old. Shouldn't the seller have been able to easily sex them? I will be very unhappy if 3/4 of my purchased "hens" turn out to be roosters! Sorry the pictures aren't great....most of them come out blurry!
