My husband is building my 4 silkies a new coop since their pen is getting too small for their growing bodies and My ""Mama" is acting as if she wants to start to "brood". Anyhow, What do you prefer to use as litter? Straw (hay), Pine shavings or sand in your coop? I like the pine (which I use now) But wondering if it will be harder to clean when we have the coop. Right now I can just let them roam while I dump their pen and clean it. I know I won't be able to when the coop is up. I used straw growing up on a ranch for horses. But Chickens are a different story. Love to hear what you use and see any pics if you have any. thanks.
