    I read the hens get to be "average size". Well, how big is average? I'm interested in knowing how tall they get and how wide they are across the back.

    Perhaps you are thinking about coop dimensions, I guess you will have to get someone with ISA Browns out with a ruler.

    After only reading your subject line, I checked with Hendrix Genetics.

    They say this about their ISA Browns at 60 weeks:

    Body weight females
    1950 grams (~ 4.3 pounds)

    Body weight males
    2720 grams (6 pounds)

    So, just about the same weight as Leghorns.
