So, let's get a better picture of the problem you are having.
You have a buck that has had offspring, but not with you, so he is proven capable--according to a previous owner.
You have several does that have missed producing litters on their most recent breedings and the one previous to that.
recent breedings would have happened in late september/early october
You don't list your location, or the ambient temps in the weeks leading up to those breedings, but it is possible heat was still a factor. It is also possible that the buck was sold for lack of performance.
Are all the animals at optimal body condition? no fat does, not too skinny?
Are the does proven?
What are their ages?
In any case, I tend to have a 3 strikes you are out policy, so if none of the does get pregnant on the 3rd try I think I would consider replacing the buck.
Yes all that was correct.
I bought the buck as a trio with him and two does. Both of which had freshly weaned kits with him being the sire when I bought them. I almost bought one of the tricolor babies but didn’t have the funds at the time. Only reason she was selling them is cause she raises meat rabbits and just had a trio and she didn’t need small rabbits. Not sure I ever mentioned but they are Holland lops. The buck is a VERY motivated breeder. So that’s definitely not my problem it’s just they aren’t taking.
Every breeding has had 3+ falloff’s. And I’ve got about 10 does total but 4-5 of those are gonna be going, some retiring and some I’m just selling my non pedigreed ones or crappy type ones then one doe had passed her three strike period. Heat coulda definitely played a key factor because I’m in Frierson louisiana (close to shreveport) and we just dropped under 50 last week but it’s been under 80 for more than a month. It’s just if hes heat sterile I’m not sure how long it’ll take before he’s not yk.
But I can confirm that 4 out of 5 I bred beginning of October did not take. There’s one i can’t confirm cause I haven’t really checked up on her so I’m not sure if she’s pregnant or not.
In summary I’ll be left with a 2 year old pedigreed proven chestnut doe, approx 1-2 year old proven non pedigreed tricolor doe, 2 almost 7 month old pedigreed bew does, and an 8 month old pedigreed broken black doe that came from my stock.
Then I have the buck we’re talking about he’s a solid black magpie I have to check his pedigree but I think he’s one or two and I have another buck he’s 5 months old, pedigreed solid black and he’s tiny, but I bred him for the first time yesterday to my broken black doe she’ll be due December 4th. And I’ve bred one of the bews to the magpie she’s due November 21. rebred my chestnut doe to my magpie due December 4th just curious to see what kind of chinchilla I could get out of em, blue/fawn tricolor doe to magpie due Nov 23 then I’ve been trying to breed my other bew to my black buck but she hasn’t lifted yet.
Let me know if you have any more questions! Sorry for the lengthy response lol
