By about 8 months you can see what they have got going on for sure.
I had an odd experience this year with my oldest pullets, all the ones hatched in February and early March molted in late fall. Some of the New Hampshires that did this still look a little rough.
With your Ameraucana, if she had a beard and muff earlier on, she should get it back as those feathers molting out and come back too. They could get pecked at, which is a stinker if you get other birds who are prone to doing that. I have never seen them start out with a good beard and muffs then lose them with age.
ok great thanks for the info.
