Hello, today I got three new baby chicks. I am using pine shavings and they seem to keep trying to eat it. They ate their food really well at first but now they prefer the shavings. This can't be good for them I'm assuming. This is how I have it set up so far, any suggestions for improvement? What can I do to stop them from eating the shavings? I've tried putting them down in front of their food dish and they pack at it for a while then go back to the shavings.
