When I purchased my first chicks I was told to use pine shavings for litter in the brooder & then coop. Since an old farmer told me that wasn't good and I should use hay. Any experts out there I'd love to here what you've been successful with. I have a mixed flock of mostly bantams Cochins, EE, OEG, frizzles, a little silkie and a few full size silkies, WC polish, GL polish and a Sumatra all young some still babies. I just want to use whatever's best for them.
