bahahahaha. I think after time in captivity there will be hundreds of breeds of Guineas, just like chickens, they come in all shapes, sizes colours etc...... Just takes time and selective breeding, I have a runt guinea and she is tiny, she has one of her feet biten off by a turkey when she was about a week old, her clutch mates outgrew her very quickly, I had to put her with newly htached keets twice because she was soo small.
