Yep, that's my Eve in my avatar. She's a year old, and for perspective that's a large snapple bottle in her mouth . She's not huge for a Dane, but she's sweet and mine. I hear she's replaced me in bed since I've been in the hospital.....I've told my honey he's going to have to either kick her...
Agree you have a lot of cockerels there.
Yep, your mature Leghorn hens have nice big combs, and so will your pullets when they mature. That's when it's all about how old the birds are. I didn't see an age, but I'm guessing around 3ish months? Pullets aren't going to have any comb to speak of...
