Yes they can sam , as i had this happen with my bird's in '83 , i brought a bird in from a fancier that had bucket load's of bunnie's runing his ground . my bird's started to drop like fly's . I knew it was cocci by the symtom's , i treated with sulmet , it diden't do the job , As I dident have time to mess about with stupid vet's or maff with their guessing game's , i consulted Queens uni , they identified a strain that is the norm to be found in rabbit's , and advised to use sulmet at doubble the norm dose , that cured the prob . the fancier where i got the bird , his also tested pos for the rabbit strain , but his bird's where in the pink .
nature is a strange thing , it will adopt & overcome
