I'm getting 30 chicks next week and am debating on the bedding. I have a barn FULL of 30ish year old hay and straw. Some if it is the "silver straw"? I don't really remember the name but I know it is perfectly dried and shiny, I also have very long and fluffy hat and some chopped up looking stuff(not sure if that is hay or straw). In my garden the long hay is very fluffy where the chopped stuff is much more dense and easy to cover with. Can anyone advise me which would be best? Again it is 30 years old and there is TONS and TONS of it. Thanks!
