Maggots Maggots can be used as chicken feed. A full maggot is 42 percent protein and 35 percent fat.
Magnum The section of the oviduct next to the infundibulum; the area in which the thick white is deposited and the shape is formed.

Mareks Desease (MD) MD is a common virus that causes internal lesions (tumors), and kills more birds than any other disease.
Mareks is a member of the herpesvirus family of viruses. It is also known as 'Range Paralysis'. The virus enters through the bird's respiratory tract.
Mareks is spread through airborne feather dander so microscopic that it can spread from one farm to another via the wind, even when no human or bird contact is made between the two farms.
There are a few different types of Mareks in chickens. The most common are eye, visceral (tumor producing), and nerve.
The nerve version has symptoms which range from slight to severe paralysis in the wings, legs, or neck.
Mareks is extremely contagious but does not spread vertically (to the egg). Youngsters should develop a natural immunity (called 'age resistance'), by the time they're five months old.
This is one of the reasons it is important to raise your youngsters separately. The older birds that have encountered Mareks and have managed to survive are carriers.
Mareks usually hits between 5 and 25 weeks of age.
Prevention: Consider the Mareks vaccine, which is available in a freeze-dried form through a few of the mail-order suppliers, and is easy to administer to day-old chicks.
Mash A blend of several feed ingredients, ground to a small size but not to a powder.
Meat Spots Occasionally found on an egg yolk. Contrary to popular opinion, these tiny spots do not indicate a fertilized egg.
They are caused by the rupture of a blood vessel on the yolk surface during formation of the egg or by a similar accident in the wall of the oviduct. Less than 1% of all eggs produced have blood spots.

Mites Once you find a mite infestation on your bird, the treatment course will vary depending on the severity of the problem.
If you have a minor problem, simply spraying the bird or dusting it once and then again three days later can usually do the trick.
A classic symptom of a mite infestation (other than seeing them through physical examination) is paleness in the comb and/or wattles.
Common or Red mite is a specie that does not remain on the host at all times. During the day, this mite finds refuge in cracks and crevices of nests, roosts, and other places in the poultry house.
At night the mites leave their hiding places, find a bird to provide a blood meal, and then head back into hiding. This parasite may go undetected unless the birds are examined during the night.
If a flock seems lethargic, the birds are droopy and weak, or they have pale combs and wattles, mites may be the problem.
The birds themselves do not need treatment. Instead a thorough cleaning and insecticide treatment of the house are recommended.
Northern fowl mite is a bloodsucker and will eventually kill a bird if left. These mites live on the bird and can be found anywhere, but especially under the tail and in the crest of crested breeds.
Parasites can be controlled by the use of louse powder (or spray) based on 'pyrethrum'. To apply, hold the bird by its legs, turn it on its back and place on the ground or a table, pressing down gently to hold it still.
Sprinkle the powder under the tail, under the wings, along the body, up the neck including the ear canals, and over the back. Rub the powder well in.
Once a month should be enough, but all these parasites breed extremly quickly if left unattended. Even if you don't observe a problem, applying the powder periodically as a preventative measure is advisable.
The depluming mite (knemidocoptes gallinae) digs little burrows beneath the base of the feathers which causes the hen great irritation and results in feather loss. Fortunately, this mite is quite rare.

Mortality Percentage of Death.
Moulting Chickens lose their feathers and get new ones, during which time they stop laying eggs.
During the moult the reproductive physiology of the bird is allowed a complete rest from laying and the bird builds up its body reserves of nutrients.
Mycoplasma Gallisepticum (MG) Contagious disease of poultry, gamebirds, pigeons, and passerine birds of all ages.
