realistically? we have 8 chicks who are about 6 weeks old. the floor of the coop is dirt and i've also put a bag of hay down in about half of it (8x10 space....2 walls are hardware cloth dug and cemented into the ground...the other two sides are wood and metal siding...it is actually a space in our tool barn). how often do you all think i should rake it out? we've had the chickens for a couple weeks now, and there is no smell nor does it look dirty in there....but i want to do the right thing as well... our old coop was only for night when we rented a house on 200 acres...the chickens free ranged during the day, so cleaning that coop wasn't really a huge issue.... any thoughts? thanks!
