This is great information. We have a 1 yr 2 month old female Holland Lop and we decided to allow our daughter to get a male recently, and breed them for pets. We bought our male from a local breeder (he is supposedly 4), who had maybe 30 other rabbits and used wire cages, and brought him home to our backyard with a wooden cage . We put them together the next day (I had read they can always be "ready" to some extent, and without pictures its difficult to know exactly what you are looking FOR, so we just went for it). He knew exactly what to do when we put her in his cage, mounted her and did his thing but we never saw her lift. So we took her out and repeated the process later. The second time he seemed to have a better grip and I noticed him biting her in an effort to get her to lift , but I could not tell if she actually lifted (I was looking at them head on) and also didn't notice if he fell off..........he may have but if so it was really quick. I really don't think they did everything necessary to get pregnant, so the past couple of days I have tried putting them together again in the mornings. It has been colder but we live in TX so never freezing or below, no snow, and he has had a few more days to get used to the food we feed and our place, but he has shown 0 interest. He just kind of sits there. She is a little aggressive but I don't think she has hurt him at all-I cant figure out why he's not trying to breed her like he was the first couple of times. I have tried apple cider vinegar (read it may take a week or so) and we will try swapping their pens for the night to see if that helps, but does anyone have experience like this? What would cause him to be uninterested? Thank you for the detailed pics-now I know to look for that before putting them together again, as she has looked like the first picture every time I have checked the past few days...ALSO-the breeder I purchased him from said she pets him but doesn't hold him a lot because she wants to make sure he does his job. Are there really steps you take with both Bucks and Does to make sure they stay ready to mate? We have also let him out to exercise (something he enjoyed a lot and I feel is good for him) but if that's going to make him uninterested in breeding I could quit allowing him some of his perks during the times im expecting him to breed.......
