    When I saw one of our chickens, Harriet, yesterday, she had pretty much all her normal feathers. This afternoon, though, about half of her feathers were totally gone, leaving her back and under wings just skin. Is this molting? None of our chickens have ever looked that bad. At first, I thought she may have been attacked, but there was an even dispersion of feathers around the yard. One of the other birds in her coop looks almost as bad all of a sudden. Is there some disease in their coop? The 3 chickens in another coop are fine....

    Sounds to me like she's popular with the roo's ,or another hen is bullying her. Some chickens will eat feathers. I don't like red breeds for this very reason. One day they're fine, the next they're bald n bloody.

    I would watch them for a while and see if she's avoiding the others , or if the others are bullying her. Sometime roo's will chase hens and pluck a feather and eat it. If this is the case, you may want add crushed oyster or clam shells, this is for calcium.

    When you see them pluck each other, sometimes they're craving a missing mineral. Hens do this a lot when they're egg shells are thin. The oyster and clam shell will fix this right up, if this is the case.

    I had a flock of RIR's do this years back. I treated them for lice, thinking they may have lice. At the same time I had 5 other pens with 100's hens, and none was missing any feathers. The RIR's were always plucking each others feathers and drawing blood. I sold the whole flock, a year later I got some more RIR's and they ate each other alive. They were worst that cannibals.

    We don't have a rooster, and there are only the three chickens in that coop. Harriet is a Barred rock, Petite( who also has some feathers missing, but usually is the bully) is RIR, and Greta is a red star(she has all her feathers). These 3 tend to not pick on each other though...
    I will keep an eye on them to see how they are doing, if any more feathers are gone tomorrow.
    Also, none of our chickens have been laying eggs for months now, and even before that they weren't very reliable, could that also be a sign of something?

    It may be the molt but most likely some kind of mite. Here are all the different mites and the cure for them.

    MITES on fowl are sometimes mistaken for lice. Actually they are quite different.

    Parasitic mites are so small that they are barely visible to the naked eve. All mites have four pairs of legs in their adult stage. Lice have three pairs of legs. Some of the mites are bloodsuckers. They may live for a long time without food. They and lice are controlled by different methods.

    Two groups of mites attack poultry. One spends the greater part of its life cycle in crevices about the poultry houses, from which it makes nightly forages upon the roosting birds to suck their blood. The second group spends the entire life cycle on the birds; they burrow into the skin, into the shafts of the feathers, beneath the scales of the legs, and into the internal organs.

    Of the several kinds of mites that may infest poultry anywhere in the United States, the commonest and perhaps the most injurious is the chicken mite (Dermanyssus gallinae). It is also known as the red chicken mite or the roost mite. The adult is not more than one thirty-second inch long when fully engorged with blood about the size of the head of a pin. Chicken mites are gray when unfed and reddish after having had a blood meal. When many of them infest a poultry house, they can be found by lifting a clod of manure off the roosts. Joints in the roosts are often surrounded by tiny, salt-and-pepper specks, which are the excrement of the hidden mites.

    After taking a blood meal from the bird, the female chicken mite finds a crevice, usually on the roost, and deposits a few eggs. She then returns to the bird for additional meals. She may deposit 35 eggs in her lifetime. Larvae, which hatch from the eggs in 1 or 2 days, do not feed but shed their skins and then become nymphs. The nymphs attack the birds, suck blood, molt, suck blood a second time, molt again, and become adults. In warm weather or in heated buildings, the entire cycle may take only 1 week. Enormous infestations may build up in poultry houses in 3 or 4 weeks.

    The northern fowl mite (Bdellonyssus sylviarum), also called the feather mite, is distributed widely over the United States, but is encountered less frequently than the chicken mite. It looks like the chicken mite but has a different life history.

    Northern fowl mites normally spend their entire lives on chickens or other birds, but they are sometimes found in birds' nests and can breed on or off the birds. Their entire life cycle lasts 8 to 12 days. They can be found on the birds during the day. They move rapidly. If infested birds are picked up, the mites crawl over the handler's arms and sometimes on his clothing. They usually congregate about the bird's vent and give the feathers a soiled appearance. Their voracious bloodsucking habits may irritate the skin severely. Heavy infestations may develop in a short time.

    Another mite that lives continuously on chickens and other birds is the scaly-leg mite (Knemidokoptes mutans). It attacks the unfeathered parts of the legs, burrows into the skin, and causes a condition like mange of livestock. It is generally found on older birds in the flock. It is less prevalent than the chicken mite and the northern fowl mite.

    Scaly-leg mites usually are first noticed between the toes. As they multiply they work their way up the leg. They cause the scales to separate from the skin and the feet and legs to swell and become deformed. Occasionally they may spread to the comb and wattles. Scaly-leg mites are too small to be seen with the naked eye, but the symptoms they produce are detected easily.

    The practice of culling old birds has eliminated the scaly-leg mite to a large degree, and it is now rarely seen except in small farm flocks.

    Closely related to the scaly-leg mite is the depluming (or body-mange) mite of chickens and other birds (Knemidokoptes laevis var. gallinae). It also passes its entire life on the bird. It burrows into the skin at the base of the feathers. It is found only on the feathered areas of the body, usually over the back and sides. The mites cause intense irritation, so that the fowl may pluck out or break off their feathers. You can see this tiny mite only with a lens or microscope.

    Most of the mites parasitic on chickens also can live on turkeys and other fowl, but they do not trouble turkeys quite so much as they do chickens. Apparently the management practices used for turkeys are not conducive to the propagation of mites. The most common mite affecting turkeys is the chicken mite. The northern fowl mite occasionally is troublesome. Both may be controlled with the same measures used against mites on chickens.

    Severe infestations of mites do more damage than lice do. Mites that burrow into the skin produce intense skin irritation and heavy formation of scabs. Such injury retards the birds and spoils their appearance when dressed. Some species cause the loss of feathers, thereby interfering with the regulation of body heat. The nests of laying hens sometimes have so many chicken mites that the birds cannot remain in them.

    Anemia, caused by the loss of blood, is common. Heavily parasitized fowl become thin, weak, and restless. Egg production falls. Young and laying birds may die. The injury due to mites that live in the internal organs has not been calculated, but may be sizable.

    An indirect loss due to bloodsucking mites results from their ability to transmit disease, such as fowl cholera and Newcastle disease, among flocks.

    For each of the four kinds of mites commonly found on chickens, a different method of attack is required. It is therefore essential to determine what species is present. If two or more species are present simultaneously, separate treatments will be necessary.

    To CONTROL infestations of the chicken mite, an insecticide should be applied to the poultry house. It is not necessary to treat the birds.

    The first step is to clean the building, nesting boxes, floor, and dropping pits thoroughly; burn the litter; and dispose of manure. Dried manure should be scraped from roosts and perches.

    This cleaning should be followed by a liberal application of 0.5-percent Lindane or 2.5-percent DDT spray to the entire interior. Lindane or malathion applied to the roosts as a 1-percent paint is also satisfactory against the chicken mite. Lindane and malathion have a further advantage in that if the birds are returned to the buildings at the close of the day, all their lice will be destroyed.

    With any of these insecticides, a second application may be required in 10 to 14 days, particularly in heavy infestations. It is not easy to eradicate chicken mites entirely.

    Because the northern fowl mite remains on the birds most of the time, insecticidal dusts and dips applied directly to the birds are effective control measures.

    Sulfur has been used for many years. The treatment of individual birds with powdered sulfur is satisfactory if liberal amounts of dust are used and if application is thorough. Dipping the birds in sulfur baths is laborious, but the results are gratifying. Dips may be prepared by mixing 2 ounces of finely ground sulfur (325 mesh) and 1 ounce of powdered soap or detergent to a gallon of lukewarm water. The feathers should be wet to the skin, and the head ducked. It is always advisable to dip fowl on warm, sunny days or in heated buildings. Treatment with either sulfur dusts or dips should be repeated as required.

    An effective and quick treatment to eliminate northern fowl mites consists of applying to the roosts or litter a chemical, the vapors of which will destroy the mites on the birds. Undiluted nicotine sulfate (40 percent) may be applied with a brush to the roosts, perches, and other roosting surfaces, at the rate of 1 to 1.5 ounces for each 30 feet of roost. As nicotine sulfate volatilizes rapidly, it should be used shortly before roosting time. About three applications a week apart are required to end infestations. The buildings should be ventilated after nicotine sulfate is used.

    Another easy and less hazardous way is to treat the litter with malathion. A 4-percent malathion dust applied to the litter only, 1 pound to 50 square feet of floor space, will control the northern fowl mite. The dust should be applied uniformly with a plunger or rotary hand duster or a shaker can or jar.

    An old, simple, and effective treatment for the scaly-leg mite consists in dipping the feet and legs of infested birds in crude petroleum. Usually one treatment is enough, but a second treatment about a month later may be required in heavy infestations.

    A mixture of 1 part of kerosene to 2 parts of raw linseed oil also may be used as a dip for the feet and legs. Repeated treatments every 2 to 4 weeks, until healing takes place, may be required with this mixture.

    For controlling the depluming mite, old, established remedies continue to be effective. The birds may be dipped in a bath containing 2 ounces of wettable sulfur per gallon of water. If spot treatment on a few birds is all that seems necessary, a sulfur ointment can be rubbed into the affected areas of the skin. The ointment can be prepared by mixing 1 tablespoonful of flowers of sulfur in one-half cup of lard or vaseline.
