You should be ok with 4 hens; but I guess what I would do is buy the other one they have in stock just to make sure (and to accommodate what appears to be the inevitable increase in birds).
I have so many ideas running through my head I'm paralyzed with what to do and how to do it!
I do know that we are going to put them side by side with some shared interior walls (my very first thought had been to put one in each corner of the coop).
Questions still pending:
* if I'm going to put them off the ground and if so by how much.
* if I do put them off the ground, do I want the floor to be lower than the natural floor of the playhouse (ie make the playhouse taller) I don't "think" I'm going to do that - with the exception of building a lift up slot under the house where I can sweep out the litter into a wheelbarrow when I do the deep cleaning.
* how big of a yard to make - more yard, more fencing and more expense
* whether the yard should go under the raised houses (if raised) or the yard should start at the edge of the houses.
* whether said yard will be covered -- I believe I will cover it because I live in rain country and if it will be covered, with what?
* I believe I'm going to have the four buildings divided in half, so I can seclude one half from the other if needed in the future (just the house, not the yard - if this was needed I'd have to alternate "turn out" to the yard).
I believe I'm going to build exterior nest boxes on the two outside side walls on either end of the combined structure. I'm thinking I need 6 nest boxes, so that will put three on either end of the structure. I do realize that one end or the other will be more popular, but not sure what I can do about that.
So any input on these ideas is welcome!
I just really can't figure out what the optimum height is!
