you're right, they are not. Omlet coops are made of virgin plastic.
I was sure they were made of recycled plastic! Interesting to see if they will make the switch now most new plastic coop makers use recycled.I've mentioned before, my sister has an omlet coop. I'm not that impressed.
What was it that didn't impress you? They are notoriously small, but people who advocates them often mention the chickens use them only for sleeping, meaning they can be outside during the whole day (not my idea of British weather I must say

We have that very problem on this property that caused a land slide thirty years ago. It's made worse by the very steep slope. When we had heavy rain in August after nine months of drought (and due to the fact that we had made some mistakes creating gutters for the old house that all dropped in the same direction) we had a torrent pouring down in front of our house after 15 minutes and it carried a lot of earth and pebbles away with it in the chicken's place. Now the land there is really in a bad state, I need to find what type of grass/weed we could sow that would help holding the soil together.It is incredible what a few exceptionally hot days and inadequate rainfall has done to the land. There are still cracks in the ground much like the cracks I used to see in Catalonia in the summer months. It was in part the ground cracking that caused the landslides when it rained hard. The rainwater just gushes down the cracks applying pressure and a lump of bank heads downward.
It's a perpetual subject of discord with my partner (who thinks I'm lazy) : I'm for minimum weeding, especially in situation of draught. I heard a lot of mystical chitchat when I took permaculture classes but one thing that made sense was never to leave a soil bare. If you're not mulching, I think it's better to leave some weeds.I've been trying slow weeding in the allotment run. Not because I'm lazy, but because if you let grow what will grow, nettles mostly in this case, they provide shade for the ground and some humidity in the soil. Bugs like this. The chickens are not keen on nettles.
