I have a small herd of 3 does and 1 buck. After a couple months of not being able to get them to seal the deal i replaced the old buck and one doe. The old ones went to freezer camp. When i got the new buck and doe they bred several times in the shared cage on the way home. I bred them again after a few hours and over the next 3 days bred the other does to the new buck. Now its day 31 since the first one was bred and no kits. They all have nest boxes and none are making nests. All are breeding age and one doe is proven, but im just having rotten luck, i guess. I have been trying to get kits since thanksgiving without any luck. I just keep feeding these guys for no return. Im tempted to put all four of them in the freezer and start over. Any tips?
