I've got NZ TAMUKs here in FL.
I do love them. My main doe is producing kits that are 6lb by 10 weeks. I've done some heavy production breeding in the past, but I started running out of cages and I don't do tractors, because there's no winter parasite kill off down here.
The TAMUKs noticeably handle the heat better than the California/FL Whites and California/NZs I had.
I still don't breed May-September. They can handle the heat, but the kits don't grow out as well because it's too hot to eat a lot.
I do have one doe that was raised on a commercial farm. They had auto feeders and wagerers, so they had minimal human contact. She is MEAN. She would lunge at me every time I tried to put feed in her dish. I have to pin her down to breed her so she doesn't attack the buck. She is an EXCELLENT mother for the first 4 weeks, then she starts lunging at the kits. I've never had issues with her kits being aggressive though. This will be her last litter and then she's going in the crock pot for a nice LONG stewing. Her sister wasn't bad at all, but died at the end of kindling her first litter.
Just saying, TAMUKs are great, but like all breeds, it does come down to the individual.
