When I put my five 2 day old chicks in their enclosure on pine shavings they started eating them. And I had one chick with pasty butt I had to fix. So I read on here to use wood pellets so I changed. I really don't like the wood pellets. They are not warm for the chicks and there is not enough stuff they like to scratch around in. Should I try again with the pine shavings? They are 3 1/2 weeks old now. Is there anything else that would be better? Thanks.
