My chin Rigsby seems to dislike my 14 yr old son. He runs back into his cage and stares out if he comes into the room,or runs and hides in the room somewhere.The other day my son reached out to pet him and he nipped my sons hand! Rigsby has never nipped before. My son has very little interaction with him(maybe thats the problem?) so it does not make sense. My husband comes in the room and Rigsby is not scared ,but will immediately nibble on the veins that stick up on my hubbies veiny feet? Hubby is scared of Rigsby now! lol! He is totally fine with my 15yr old daughter and I:hmm:. Could he dislike male humans?
