Hi. We're on the west side of Los Angeles and we're super excited/in love with our new chickens. With my 6-year old daughter's blessing, I converted her rather large play structure into a chicken coop. We have two Australorp/Orpington hybrids, 1 pure Black Australorp, 2 Red Star Sex Links, 1 Plymouth Barred Rock and 1 mystery chick that was incubated and hatched in my daughter's first grade class. (One reason I'm posting here is so I can get out of the newbie phase and post a picture of her (hopefully a her!) so someone can tell us what the heck she is. And I guess as long as I'm here ... I'm assuming since the floor of my coop is dirt (there's actually still a bunch of grass) I don't need the kind of many-inches-thick layer of pine shavings at the bottom of their coop, do I? Right now it's just sprinkled in there and I was thinking I would just sprinkle more on as needed, maybe every week or so, and then rake the whole thing out, I don't know, once every three months? Does that sound right?
