I have my 26 chicks in 2, 50 gal plastic boxes (13 in each). I have been using all pine shavings for the entire bottom and it only lasts about 3 days before I really have to change it. It is fairly cheep but seems to be a lot of waste. I saw in the feed stores the chicks are in small wire cages...is it wise to keep them in cages instead of the box, and only put a small section of shavings ? Also, I read that the chicks will damage there feet over time if on slippery or flat flooring...is this true ? Thanks for the help.
