We bought an omlet walk-in run.
It's 6ft x18ft and 6ft-odd tall.
DH got a pension from work (he's still working but his pension scheme has a sum at 60), so we decided to upgrade.
It was easy enough to assemble, but I've dug it into the ground by about 4-6" to make it a bit more secure.
I tore apart the old run, but we've still got the old coop because it's fine. Although, we had to split it in two and create a pophole at the back because Blossom can't stop bullying the newbies.
Antway. It's big enough for 6 hens to live there permanently, we're going to "landscape" the rest of the tiny garden to look goid for humans, and we're putting plants around the outside - some for smell and some that the hens can eat through the bars
