If they are free ranging, they are fine with that routine. If they are in a pen, they won't be able to find enough. I don't leave out free choice for my free rangers. Just my cooped birds. Plus you've been doing it your way all along I assume and you have 3 year old healthy birds, so who knows. Can't be messing up too bad. ;-)I feed in the morning and they forage the rest of the day. But when I feed them, I really feed them a lot! I've felt that I'm feeding too much, but, to be as educated as I am, I'm now embarrassed that I might have missed the boat on this. You know, it takes some humility to admit that you've messed up. I'm quite humble. Thank you so much.
But we, their kind and loving keepers, do have to supply it for them. They can have my share.
