I knew what you meant. These two girls didn't even hold onto it for their juvie molt, it was gone that quickly. I've got one Olivia egg in the bator for lockdown tomorrow. Fridge egg, and yes, that's all your fault!Sorry, I should have been more clear..........I worry about the birds that do not lose the mossy, if it goes away when young I don't mind. I have not seen a problem using the birds that have mossy while young. I will not use a bird that shows mossy after first molt into adult plumage.
