I don't have any handy, and don't want to out myself too much, but this is how we approached the problem,
I was first asked by a client to come up with a solution as they were often very late home,
we made a large cube, with a sloped roof, we used galvanised steel sheeting, insulated with triso , internally industrial fridge panelling, at the back lower sloped side, we had access panels to get to boxes, with dowel perches across front and side,
we set four large 9/9 posts in the ground, on the cube we added large industrial hook eyes, to each corner, the cube was placed in between the posts, on each post we put a line of industrial hook eyes, with locking boats cleats at the bottom(we got most of the kit from our local chandlers, which has a second hand section)
we use a flex cable with carabiner clipped onto each of the bottom corner of cube, cable goes up the side of the cube, then down the poles,
on the front we added another hook eye, below the door, made very long pole with random small dowel running up each side, add L shaped pin to end of pole, rest the L into hook eye on house,
every day crank house up a foot, the hens start off on the floor, and move up, cube can come up and down easily, jet washable, we have a back step for getting eggs easily,so we only get house down for cleaning,
we have done various versions, I came up with a system that meant you could have it all on one hand winch, go and chat up the local chandlers, they love a good design challenge,
we grow things up the posts to help soften them, they look brilliant within two years,
here is one idea
