I actually don't have any idea about her age. She isn't a pullet -- she was laying for her previous owner -- but she just started laying for me on the 22nd.
As for the rocks, they are doing just fine. They're very cute little buggers! I *think* they've started laying -- can't tell if it's them or the bantam leghorns, but SOMEBODY is making ittybitty white eggs.
Ohhhhh, wait.....rocks would lay brown eggs, wouldn't they?? I just answered my own question!
