Hi!! First time chicken mom here to 10, 14 week old RIR’s. Right now their run is covered and the coop is inside the run. They sleep on a pallet on the roof of the coop by choice. I used pine shavings in their brooder and then in their run once they grew older and switched to hay when the pine shavings weren’t available. Oh, there is a base of sand in the run. I am concerned about impacted crops as my girls love to eat the hay. My questions are as follows; Can I use pine shavings in the run (mixed with food grade DE and coop freshner) and offer them just a small spread of hay in part of the run to play in (they love to scratch through it)? Also, how often should I be cleaning the run? Do I just pick up the really poopy areas and then add shavings? How often? Just a note, I switch out the hay often because I’m in Florida and it’s humid even now in the Fall and I am concerned about mold.(Which is why I’d prefer to use pine shavings) Any advice and/or ideas are greatly appreciated as I love my girls dearly and want them to be as happy as possible!! Thank you in advance!!
