Second, some minks have a strong sense of territory. When other minks are found in their own territory, they will make a fuss and fight for their position. However, if the disturbed mink can be obedient, it will take some time to be basically fine.
Thirdly, I don't know what the questioner means by fighting. If you jump up and make noise, it's really interaction between minks. If a mink bites another mink's neck and leaves, it means that the territorial right is going to be contested, and the lethality of the mink is still there. Real fights are basically bloody, and the wounds are deep and need to be stitched up. If it's just some small scars, it's really the result of carelessness.
Fourth, minks will hiss when fighting, scream when bitten, and don't keep them alone until they see blood.
Ps: There are five minks in my family ... only the boss. ...
