The angora does turned out not to be pregnant. I suspected as much when I originally got her home and realized just how emaciated and matted she was, but I still hoped. She was very expensive, but I'm glad we were able to get her and give her proper treatment. She's back up to normal weight now. We're planning to pair her with Marshmallow next spring for angora babies.
I tried my New Zealand buck on two does last month, so we'll see if he did his job. If he did, we should have two litters by the end of next week. One litter of New Zealands, red dad to white mom (1st and 2nd place in their categories respectively at the 2013 Crow Wing County Fair), and one litter of New Zealand/Harlequin cross. No nesting behaviors yet, but we'll keep watching. These would be our last litters before winter, and no planned breedings until spring. If our buck fails to produce, he'll be sold and a new buck purchased in his place.
I picked up some new cages today too. Eventually they will be used for grow-out cages for baby bunnies that don't sell right away, and for the angora bucks, as I expect them to be quite big. They've already doubled in size since we brought them home.
