I just mased some up for mine that are a little over a week old (4) and my new polish that is almost a week old. I couldn't get them to eat it out of my hand but when I put it in the pan, the littleist one (poish) ran ringt over and on it and started chowing. my larger chicks just watched her for a while and then finally caved, but one of mine isnt interested in eating it just running through it while the others are eating....
