I have five guineas, three boys and two girls. Today I discovered that one of my boys ears has two chunks taken out of it, which seem to have scabbed over. It must have happened in the last few days. I have removed him for the night, and put him in another hutch with the most docile of my boys (i.e. the least likely perpetrator) so he is not alone. I don't want to remove him from the group as they seem to get on so well (or I thought they did) and behave a bit like a small colony. I am so upset about this, I really don't know what to do. Advice, please...!
