I have all my 4 rabbits in a repurposed chicken coop but now I have three litters between the ages of two and three weeks and each litter is 7 kits. two litters are i dont know what breed but the does are supposed mini rex but the people i bought them from keep different breeds together. The older litter is 3 weeks and is new zealand. so, I bought a 100 ft roll of 36" hardware cloth and the j clips and everything else to build some cages. is 36x36x36 over kill or is that a decent cage size? im building a long row 15 ft of cage divided in 3ft sections.
