I purchased a little place this summer that has a chicken coop on it. It hasn't been used for almost a year or maybe longer, but the previous owners kept some sheep in the coop as well as chickens. It has a dirt floor. I've been able to get the majority of the sheep manure out, and will scrub all the old chicken poop off the roosts & walls before winter comes (I plan to get chicks in the spring). I'm wondering how careful I should be with getting all the old animal droppings out, and if I should remove some of the dirt floor as well. I don't think sheep have any parasites that might hurt chickens, but previous chickens might have left some in there - would they still be able to infect my chicks after a year+ with no hosts to live on? Any hints on whether I should sanitize the walls or if a good scrubbing with soapy water would work? If I should sanitize, would bleach in water be OK if it has a few months to air out before I get the chicks? This will be my first chicken experience, and I want to start out in a good position to raise a healthy flock. Any ideas will be very helpful! Thanks!
