I have a blind sow called Princess. She is absolutely fine and finds her way around the hutch and run really well.
I got her at 7 weeks old because the breeder was giving her away and then 7 weeks later she presented me with a litter of 2 babies! :{ One was doa and the other I have kept here with me and he is called Junior. He has big bright dark eyes and can see, which was a relief.
Anyway, you do have to treat a blind piggie slightly differently.
1. Never leave the hutch door open while feeding as they wander around and can fall out.
2. Always speak to him or her before touching or picking them up.
3. Always give them their own portion of veg, fruit etc. as sometimes it is a case of they have something lovely to eat and then out of the blue it has gone, because their companion has taken it. That is very confusing for them as they just don't know where it has gone!
4. Bond them with a companion and group and try to keep it that way.
Apart from those 4 things that spring to my mind immediately, I think that is it really.
Princess is a delight. I love having her and caring for her as I often think what would have happened had I not had her. Apparently, the breeder would have had her sleep if she was a boar.
All the best with your new little one. Is the blind piggie in the rescue section of P&H?
PS. Princess loves having a bath as she has no fear of the water, she just gets a warm nice feeling I guess. There are some photos and a thread on her under the rescue section not long back.
