bro, my rabbit kids (between 1 to 2 month age) are dieing (10 to 100% mortality ) in every batch. post mortem lesion is red lungs (should be pink). I am feeding them adlibtedly daily moisted mixture of fresh wheat flour + mustard cake (24 hours soaked) + salt + mineral mixture and seperately fresh grass. water in bowls are changed in every second or third day, they are kept in GI wire mesh cages. I m using STREPTOMYCIN (but it does not work every time), Penecilin, enrofloxasin, piperazine, albendazole gave no positive result.
