I've never killed anything in my life, and I don't feel it is an experience I need. Worst case scenario, if I have a bunny screaming in pain from an injury, my mum's boyfriend is a hunter, and lives less than 5 minutes down the road. For my peace of mind(and ability to sleep), I would much rather take him into the vet and pay the 20$ to have him put to sleep. And as far as it goes, while bashing him in the head is the financially cheaper option, I don't know how it would be less traumatic to the rabbit than being put in a box and given a sedative, then injected with a drug to stop his heart. Especially considering how badly my hands are shaking at just the thought of doing it.
As far as it goes, I think the bunny was born blind. Previously, he did react to my hand reaching into the cage, but he was always in a group with his siblings, and could have taken his response from them. He never ran away from my hand coming in to grab him, and only struggled when I had him IN my hand. Those struggles were always token struggles, and he calmed right down when he had a firm surface under his feet. He never ran up to the dog, which all the other babies did. He doesn't seem upset or confused at all, like this sight problem is something new that he is trying to deal with. He doesn't respond to the "flinch test", but the other babies do.
I've moved Dobby into another room. I contacted the woman who was planning on buying two rabbits for her sons' birthday and told her I couldn't sell to her. I pulled Lily from the cage and moved all the babies but the cloudy eyed one to another cage. Just enough cage space for everyone. I guess now I just wait, and if in a month, nothing happens, sell all the rabbits.
