That is a plus then for the Noirans; my biggest worry are those high production breeds. Not sure on the Azures, they say they lay 200+ eggs a year.They don't spend that much time at the feeders. They probably eat less than my other bigger chickens which is logical since they are not laying.
When they are out and about, they are good foragers. But, they seem to spend a lot of time just doing nothing - babbling softly to one another or looking at the scenery.
I'm not sure, it would depend how much harco and how much Marans they have. They don't seem to be early layers as most production breeds are.
