You will have seen photos in the Build section, that I have a block of 9 breeding cages 3 x 3.
They measure 25” wide x 14” deep x 19” high. Given the choice I would have slightly smaller cages as I believe there is a lot of wasted space in the height. Ideally 24”wide x 14” deep x 16” high – this would allow me to get another row of 3 cages in to the block making 12 breeding cages in the block, and believe me when I say that I am in need of the extra cages.
Here are a couple of photo’s of how I set up the breeding cages, the nestboxes are not fixed on yet, so this will give a better idea of how they look.
