As Samantha draws said, rabbits are induced ovulators (they produce a hormone in response to being bred, that triggers the release of their eggs). The hormone production peaks about an hour after the doe is bred, and drops slowly afterward. If you have a doe that has had smallish litters, breeding her again an hour or two after the first successful attempt will cause the doe to "peak" a second time, which may trigger the release of even more eggs. This effect only works if the breedings are within an hour or two of each other.
Some people will breed a doe twice in a day, several hours apart. The argument for this is that a doe may only release eggs from one side, and perhaps release them from the other side on the second breeding.
I'm generally too busy (or too lazy, take your pick) to take does back to a buck hours later. If a doe accepts a buck, I leave them together, unless the buck gets too rough or the doe gets hostile. I usually take the doe out within an hour. I can't say I have ever had any problems with litter size, except with older does; with them, I may put her in and take her out, then repeat an hour later. A few of the does I have tried that with refused service the second time, when they were quite willing the first.
Rabbit does don't do "heat" cycles, but they do experience hormonal peaks and valleys. Before I try to breed a doe, I flip her over, and press just in front of her genital opening to expose a bit of the inside of her vulva. If the color of the exposed tissue is pinkish, I put her back - she most likely won't breed, so I don't waste my time or the buck's. The color I'm looking for is a bright, cherry red, though some of my does never seem to go past a deep rose color. Purple indicates a doe that has passed her hormonal peak, and has aging eggs; she may breed, but her numbers may be low. I have never tried force-breeding a doe; I've heard that the odds are rather poor for getting good litters that way.
