I have 3 doe 1 buck doe #1 & 2 have had 1 litter each and doe #3 has never took i have visually saw doe #3 get breed 4 diff times.i have left them in for 2-3 mating (time 30 min). I have left them in for days together and nothing. i bought these rabbits in oct fully grown age bewteen 2-3 yrs .over the winter they wouldt take i tried boss apple cider.march they starting taking again but no babies.i just rebreed them this week all very willing with the buck he covers them repeatedly.doe #3 seems very eager to breed but has never took.doe # 1 & 2 had little in nov.what can i do im bout to start over i called the local vet they want 67$ per 2 rabbits to chehk them out but honestly they acted like there wasnt much they could do to help with fertility issue.i think the buck isnt the problem he is a try hard even when the doe wouldnt lift this winter he just going and going.please help first time with rabbits very frustrating.i have them in wire cages 30 ×36 feed pellet 18% rowe feed all the hay they want clean water.ive tried to palpate with no results.
