In Katie Thear's book the Manchurian Golds and Italians are refer to as being the same but your pictures show that is not so.
Is it true the Manchurians were developed in the US by Marsh Farms?
Do they both have a lethal gene?
Breed an Italian Gold male that hatched from Stellar eggs to 7 Jumbo White females and got some great color varieties including Italian females, fawns and ?fawn tuxs? (cute but have not seen or read about anything like them). They are two weeks old but thats what they look like. Not one white which just goes to show that white is recessive.
What variety do you normally breed golds to avoid the lethal gene?
