Does are as individual as people are. Some does mature early (as early as two months) others can wait up til a year. Does that mature slower test your patience.My tan doe refuses to breed. Do I slip her a roofie or something?
Things to do with scared young does.
1. put them near a buck or between two buck cages.
2. switch cages with a buck for at least overnight
3. wait for them to act like adults rather than babies. (this should actually be first)! Adult rabbits act differently than immature rabbits. So wait until they act like adults.
4. give a LARGE space for them to run around in. A large pet run often works perfectly.
5. expose doe to buck in the evening one day, in the morning the next, and the following time in the afternoon. Rabbits often breed well in the evening/at night (8-9 p.m. or right before evening chores) but in 20 years of breeding rabbits I've had some that would ONLY breed in the morning and others ONLY in the afternoon. those oddballs make a note of so you don't waste your time next go round.
6. She might not like your buck. So let her meet another fellow and see if that helps.
7. check vent before and after you have her with the buck. I've known some buck/doe pairings that seem sneaky. You'll be looking for a purplish vent before breeding and afterwards for a semen deposit.
8. if your buck is young and insecure about public breeding but overall a steady, easy going sort, sometimes you can leave them together in a largish area (that is secure) and just wait until she starts to squeak at him a couple weeks later. (the squeaking is I'm bred, leave me alone). Feed her hay every day (or just access to bedding material) until she shows interest in it and give her a nestbox. Needs to be a large enough area that they can mutually ignore each other though or there might be fighting.
9. car rides down bumpy roads with both in the same carrier.
10. take her to a rabbit show... or some place with LOTS of different bunny smells.... kicks the hormones in to high drive.
Most of all though, be patient.
If all else fails (so by the time they are 1 year old and still refusing) make a weird change to their diet. Doesn't much matter what. Add some BOSS, give some manna, if you feed hay, feed a completely different type, give a cracker or two, sometimes changes in diet help switch a doe's brain to on.
