Mine where one in March I have 5. Three have big droopy combs.2 have smaller combs.They are all about the same size and weight . just different features . like it because you can tell them apart easier.
She is probably something different.Some of my leghorns are from tractor supply.They are all white with red combs and wattles.We were suppose to get all leghorns from Tractor Supply.But we ended up with 3 cornish rocks. So you could have gotten ? lord knows what.
I have 9 Leghorns.16 wk old. I absolutely Love them. They get let out of their coop,at 6 am.At 7.30 pm ,they are ready to go in.They just hang out in the yard all day.They don't let any other bird or squirrel in the yard.
