Webpage shows acc-44 nests up pretty darn high....maybe they've learned and lowered them?Good info @aart. Unfortunately, too late! I did debate going with a 6 x 4 foot coop, but I was seeing a lot of info that pointed to not exceeding 4 sq.ft. per bird, in climates with cold weather. So, 4 x 4 foot coop is purchased, assembled, and painted now. It's an ACC-44, which has the nesting boxes probably about 24" from the floor (I'll have to go measure tomorrow). The reason I went with a purchased unit, rather than building my own, is that I figured stuff like nesting box height was already figured out. Being new to this, and not knowing what's needed for a good coop design, I figured that was the way to end up with something more functional the first time around.
I did notice the door is only 1.5" above floor, which I did not like. I figured I'd just add a plywood lip to inside to keep bedding from getting tracked out and interfering with door closing.
I can install the roost bar at any height, or even have more than one. They show it going at same height as nesting boxes, but I could easily move it up. I'd just have to provide a means for them to get up/down, due to the shorter floor space. What do you think?
4' is hard to work with, my coop partition is 4' x 6', the 6' roost with narrow(1') poop board is only 30" high and I put a 16" concrete block on floor for a 'step up'.
If I need nest in there I use a portable floor nest(14x16x16) that goes under the roost board. But I only use the partition coop for new chicks and sometimes 1-2 older birds that need to be temporarily isolated...my partition wall is removable. Sorry, all that doesn't really help your situation.
Usually a ramp is in order, not sure you could fit one in, but maybe a well placed 'step' could be devised.
Pics of your actual coop interior might help.
