I'm trying to determine which of my Roo's fathered which chicks. I'm trying to use the chicken calculator. Would a speckled sussex be considered a Partridge or a Jubilee , or something else? Roo's are blue orp and wellsummer, hens are blue orp, barred rock, speckled sussex and maybe a white rock egg got in there by accident. I can't seem to figure out the 3 white chicks I got.
