My Leghorns look like that too. Most of them anyway. Short and stumpy with big bodies. I also have some that just look like a normal sized chicken. Most pics I've found show both kinds for Leghorns.
Hi my name is Andi and I live in Oklahoma. I've actually had chickens for about 2 years now but just a few at a time. I have become a little more serious about it now, lol. I went from 7 hens to 64. Ack!!! I have mostly Leghorns and Marans with a few Cochins, Easter Eggers and Olive Eggers...
