In the first year raising rabbits I had an Myxo outbreak, once I realised what was going on I seperated the survivers and had a rabbit in every room. Only my little black Fury, living in my kitchen, made it. Kept her indoors until spring, bought a second "doe" early in the year and when "she" managed to break out of her cage I was amazed how well those two got along. A month later I had 5 more rabbits in my kitchen.
Very inconvinient situation They all moved out into the hutches once it was warm enough, Fury got retired from breeding at 7 and is a happy, 11yo outdoor bunny now.
I kept the buck since I needed one anyway, his heart failed after a fox attack 4 years later.
Missexing is fairly common, but you have quite a string of bad luck there
. When I sex my kits I always get a second opinion (there are two other breeders in my road), and I also watch them closly, I let mine out of the hutches for grazing - if a doeling runs down the ramp, does a short digging burst making a fist sized hole, and hopping away - high time to check genders again, that's something bucks do, when does dig it's a tunnel.
