Finchbreeder
Songster
He is a Gray normal (the original wild type colour) she looks like a silver or dilute. (they are hard to tell apart in photos) So both of those colours are likely, but he could be carrying a sex linked fawn gene - breeding like this is the only way to tell - so if you get a little fawn she will be a daughter. Can't see an odd white feather or toe so probably no pied genes. But there are still other recessives they could both be carrying.
