Hello....I am wondering what are the possible combinations that will produce a solid white polish bird? I hatched eggs that were from white crested black and silver laced...supposed to be 2 different pens from the breeder but somehow I ended up with a gorgeous white hen. I lost her...she was egg bound with her first 4 eggs all backed up inside . I can't find a breeder of solid white so I'm wondering what crossing can produce this. The breeder I got the eggs from has no idea (?) Interestingly enough...I got white crested blue eggs from someone and I ended up with a blue splash...she is white with a few blue feathers here and there.
