I'm new to chickens and my cornish roasters are very ready to get outside. I've already got the coop built, but i'm not sure what to fill it with (aside from the dirt it's setting on). There seems to be quite the division between straw vs pine shavings/chips vs hay..and since they're only going to be around for a couple more weeks, what's the best way to set it up and make sure they're happy? (I'm getting overwhelmed with all the available info ) I have the space to be free-range too, but still need to get their water and supplementary feed set up too. Also, what's the best way to keep it clean? These guys really put out some poo.. I'm not sure if it's set up right to do the deep litter method i've read about and i don't want to accidentally hurt them.
