Hi experts! I have been reading about mutations, Cutelilbudies webpage is awesome! But of course I still have questions. Will a normal green ever have blue tinged feathers around their vent if they don't have a violet factor? My Alex is a normal dark green but he has blue feathers around his/her vent so I am wondering if he could be dark because he has a violet factor. Someday if I ever decide to breed I could have so really beautiful violet budgies if he/she has violet too!
