So far Ive been using napkins, paper towels, and newspaper, but I have pineshavings underneath. Every so often one of my wiley chicks finds a way to the pine shavings. Then look out, its a pine shavings party. Everyone shows up and there is this frensy to get all the pine shavings you can. I start stressing, no, no, you'll all get impacted crops. Stop......!!! They are one week old today. Is it ok to let them onto the shavings yet? Have any of you lost chicks to this madness?
