Ok well I had 3 Guineas and 1 would always lay an egg but they look identical. 2 of the guineas were killed and I have had 1 left for about a year now. I found a add for a guinea and thought I may buy mine a friend. Mine is a boy I am pretty sure! Here is a picture of the guinea for sale, they dont know what the gender is and neither do Does anyone know or is it to hard to tell?
