Ok, we have 3-4 week old chicks in our downstairs brooder who were initially on newspaper with paper towels over that. We switched them to just newspaper after about a week and they had good solid legs. The problem is they have been really eating the newspaper this last week. We switched them to straw bedding today and a larger brooder and they have eaten some of the straw. This doesn't seem like it would be very good for them and maybe even give them impacted crops. Should we switch them to pine shaving? Just not sure what to do with them. They have free choice chick starter and can have all they want. We have not started them on grit yet since we are not giving anything but their crumbles. Please help!! Thanks!
