No pictures because I'm in bed, but I converted my old rabbit hutch into nest boxes. Cut off its legs, removed the doors, used the solid sleeping compartment door to divide the other part of it into two. Voila, three nesting boxes. And being an old hutch the roof raises for easy access. Although I do have the perch sitting on it.
I took apart the door frames and used them, along with an old pallet I found dumped in the park (heat treated, not chemical treated, I checked) to make the perch, some ramps to get on to the hutch (ex-cage girls will have weak legs and wings to begin with) and steps in and out of the shed.
The old rabbit water bowl holds their grit too. The only things I've bought new are the waterers and a feed trough. The coop itself is a small shed, so I wanted things designed not to be kicked over too easily. Everything else is repurposed. I'm even going to use the hay wrack in the run (an IKEA plastic bag holder) as a green treats holder. They're gonna have to work for those greens.
Next up I've got some nice branches that have been stripped of bark by the buns to turn into swings. I'll try the CDs on strings idea too. And with the few bits of pallet I have left over I'll build a nice little sand box... or I might use an old standard sized litter tray, but I'm thinking it might be a bit small.
I'm growing plants in "pots" in the front for the chucks and the buns (maybe I'll get the odd courgette to myself?). The "pots" are those big plastic veg crates. I scavenged them from work. The best thing about them is that I can move them around. So at night, before the seeds had sprouted, I could stack them all up to stop the local cats and the little free roaming terrier digging them up.
Even the potting material was free; bunny litter compost. I have three compost heaps on the go. Rabbits poop a lot. Can't wait to get the girls and get them working on the heaps!
