Hi,
I have an Omlet cube and love it. I have it on the outside of a flight protection pen. Around that I have picket fencing so they can free range, but are restricted.
I let them free range completely, albeit, fencing off the borders when am around as I have three very good pheasant, magpie, pigeon catchers in the shape of Burmese cats, who cannot be trusted to have a pop! ^ months later they still stalk the chooks!
The cube is easy to keep clean, too many friends have had red mite in their wooden ones and it has ended in disaster for the hens, I didn't want to risk it so opted for the cube.
I went to a hen party and got hooked. have 7 chickens, 4 came from Omlet, - 2 Mrs Pepperpots -Bovan neras and two Gingernut rangers -Bovan goldline - one got lost, I added a speckeldy and an amberstar, and then rescued two white sussex.
I am still getting 4-5 eggs a day at the moment, some 25 a week which is just about enough to not have to buy eggs!
It takes about 10 minutes a day for general cleaning, feeding, heath checks etc and then every 6 weeks I clean out the pen completely. I used Aubioise -horse bedding on the floor of the pen and the poo disappears like magic! I then offer it on freecycle and have people queuing up for it for their allotments.
My minded children love collecting the eggs, feeding them treats etc and it is a great way to really instill hygiene and handwashing.
I'd love to get some more, but 10 would be the max in a cube, they do have lots of space and seem to rattle around in it!
Mine are 100ft down the garden, just because that is where there is lots of free space.
Go for it, I wanted them 3 years ago and we had the big Avian flu scare, but then wished I hadn't left it so long to get some.
