My four-day old chicks seem to love to fill their food dish (the steel type with 8 small holes) with their pine shavings. I give them fresh food every morning and within an hour or so they have filled their holes up with pine shavings. I don't think they are starving so I assume they are pecking their food out. Any ideas? The waterer seems to get filled with shavings as well but I perpetually keep cleaning it. I don't mind wasting water but I don't want to keep dumping their food and refilling it.
