Hi, how cool is that! We got our first ever from the local hardware store, and then I wanted Swedish Flower Hens so I got fertile eggs off EBay and hatched those, too. We put ours in pine shavings from the first day. Yes, they pecked and maybe ate a few little bits, but they never got sick. As long as you're poking your finger into the food as though your hand is 'eating' the baby food, they'll eat that, and you've showed them where/how the drinker is, yes?
I fretted about them "eating" the pine chips too, but they were - as stated - in them from the get-go and they were fine. I think if they do eat a few, it doesn't harm them. I worried, my partner didn't, and all are running around out in the run now! Here are ours, and you can see...pine shavings!
