Okay, so we have year old hens. They've been on layer rations since last fall or so. We also have pullets. So far, I've been able to keep them eating different foods, but now they are all mixed in the run AND we will eventually be adding our banty ducks which are only 2.5 weeks old right now. The brand of feed I use is good for chickens and ducks (I don't know if this is common or not) but they are different ages. How the heck do I keep everyone eating the right feed? I'm sure you folks have figured this out, yes???
