so a couple months ago I ordered 20 fawn and white indian runners from ideal hatchery. when I got them I sexed them and get rid of all the males except for him, I liked his black bill. they are now older and they are not indian runners, I have 3 full grown and from the coloring these guys look more like Saxony. what I'm trying to figure out is how this white guy got mixed in, he came with the order but I'm not sure if he is Saxony as well and just has a couple gene mutations or if he is something completely different. my intentions were to breed the indian runners but that's not gonna happen now lol so I'm thinking I'm gonna breed these guys but with this white one I'm not sure what I'm going to get...iv been getting very frustrated trying to figure out what they are as I can not find another duck that looks like him. he has some blue mixed into his feathers mostly in his face.. someone help please!
