Oh, My! I am new to this. This is my first season with new chicks. I have been cleaning their house, sand box and beds every other day. Will it hurt them to do that. I am a bit OCD about cleaning and don't think I could possibly let it go more than a week. I have 6 Bantams, 1 Wyandotte, and I believe 2 white Cochins. The ones I believe are Cochins were supposed to be something else but did not turn out that way. I still can't tell the hens from the roosters. I have only one trying to crow so I am certain it is a rooster. They are about 10 weeks old now. They have started to free range now too.
It depends on what your procedure is of "cleaning". It doesn't have to be a sterile laboratory, but I'll give you an idea. Chickens need to be in contact with their own feces and other organic matter within reason to build a strong immune system. Molds and fungi, bacterial build-up, rancid or discarded feed, and dead animal carcasses should obviously be avoided. I know folks who use sand in their chicken yards and swear by it. It keeps down fly populations, and is absorbent. It is easy to remove droppings like cleaning out a cat box. The amount of work depends on how many birds you have and how large your yard is.
I built my coops for my own preferences. I have one coop with a concrete floor and two with wooden flooring. The roofs are corrugated steel, there are windows/vents and no areas that leak during the rainy season. I use pine shavings on the floor area and nests in my coops. I have large yards of soil and grass. There are certain areas of loose soil they prefer to dust themselves.The location has good drainage and is large enough to keep birds from destroying all vegetation growth. I keep the yard mowed and pruned to deter overpopulation for slugs, snails, and other vectors for parasitic worms. I intend to add sand and topsoil in the yards this summer to improve drainage.
I do a quick pickup with a dog pooper scooper and a small steel rake under the roosts each morning. It only takes a couple minutes. This allows me to identify potential digestive problems in addition to preventing the build-up of manure. My coops don't stink, nor become moist caked up with manure.
About every 3 months, I remove old shavings, shop-vac the coops, disinfect with Oxine or Biophene, let dry, then treat all cracks, crevices, floors, walls, ceilings, nests, and roosts with Ravap EC or Permethrin concentrate, let dry, then add fresh shavings. I do this while chickens are ranging and they are allowed back in the coop when I am finished. I've mentioned it before, but just thought I'd give you an idea of procedure. I rarely have sick birds and never have rodent, mite or louse infestations.
