4 month old Leghorn is HUGE

[Jill Cagle]

I have 2 Leghorns that I got about 4 mos ago and they are huge!! They are almost tipping themselves over. HELP

They are not Leghorns; my guess is that they are Cornish Cross.

X2...did you get them at tractor supply or similar feed store? Post pics to confirm.

Post a pic, I'd say you got CornishX as well.

Could you post some pictures? I agree with @sylviethecochin : they sound like Cornish Rocks.
Are their ears white or red? How do they act? Are they active? Do they eat a lot more than normal chickens?
