I have just been in to give the gps some veg and only the more timid of the two came out to get it. When I lifted the shelter up to check if gp2 was ok I found him dead with his ear and eye missing. Why would gp1 do this? They are both boys. We have had them about 4 months and there has never been any conflict between them. Will gp1 be vicious now? I just cant understand why this has happened
