I used these to keep my birds off the floor for winter (I used to breed a lot of Pekins)
The older one was originally for quail, it has five compartments and is accessible from the front and back, the other 3 my dad built, 2 are double and 1 is triple.
Trailer needed for collection
Older one is £50 SOLD
2x Double are £80
All have wire floors in them but could be modified in the back to have solid floors, I just found it cleaner to have wire.
