sounds like hormones are kicking in...also, and this is just my experience... but we used to breed polish bunnies and they were generally not a friendly breed. We had one male that was a sweetheart but the does were all very territorial and snippy.
There are exceptions to every rule, but after raising and living with rabbits for 45 years I truly feel that there are temperamental differences in the various breeds. In general larger breeds (except checkered giants) are more docile, likely because those who breed large rabbits are less likely to put up with a large aggressive bunny than someone who is breeding 3 lb rabbits.
I've bred several breeds and kept others as pets and there are HUGE differences in temperament. Again, this is in general, there are sweethearts and stinkers in every breed.
As far as discipline, a can with a few coins or rocks in it works wonders to train a bunny away from certain behaviors. Everytime they engage in the unwanted behavior, shake the can. They don't like the noise or the startle they get when they hear it and will avoid the behavior that leads to the noisy can. Also, they don't associate the noise with you the way they would if you used your own hand to discipline them so they tend not to try to fight back or avoid you.
I got my MIL a female Polish that is currently 3 months old when she was 9 weeks old I had to force feed her for about a week as she completely stopped eating and drinking and since then she has become “bitey” she bites my MIL, my 4 year old daughter, and pretty much everyone else except for me and I was of course the bad guy when she was sick I would love some advice on how I could possibly stop the biting as my vet said to just squeal when bites and that should deter her from biting but it has made it worse! So any advice on deterring her from biting the humans in the house??? The picture is Gingersnap the habitual biter!!
