I happened to be there at dusk to see that my ginormous Buff Orpington hen is having issues flying up to the main roost bar . I'm not sure of its height, but obviously it's too high for her. The other, lower roost bar is commandeered by the bantams; they're little hellions & won't share with the big girls. I'll be making a 'fat ramp' for her largeness, a ladder, that she can use to hop up to the main roost bar. Big Mamma is the only one that has issues flying up - the others fly up handily. I want to say it's about 4' high. She's been fine 'till recently...just getting bigger & bigger! The flock ranges all day & returns to the coop at dusk. This particular hen is an eating machine...more so than the others by far! Wondering what other owners of big ol' Buff Orpington's, or other large breed chickens, find is a comfortable roost bar height for these moose-like gals to fly up to? Thoughts, comments, ideas all appreciated!
