Hi all, My babies are 1 week old today. I still have the papertowels over the pine shavings in the brooder. When is it ok to take them off?? They did find them the other day and had quite the party in there! Should I be worried about them eating the shavings at this point? They are on chick starter food and do not have any grit. What do you think?? Thanks! Kim and the wee ones!
