My Partridge Cochin hen developed a severe instance of pendulous crop a few weeks ago, the severity of which required that she hold out seat to sleep. There's non much that tin sack hold out done to preclude pendulous crop, but its progression powerfulness hold out mitigated inward some instances. This article is dedicated to sugariness Bertha's memory.
WHAT IS H5N1 CROP?
A chicken’s crop is a small, pocket where nutrient is stored earlier continuing downward the digestive tract. It is located slightly to the side of its correct pectus muscle. When a chicken picks upward nutrient amongst its beak, the natural language pushes it to the dorsum of the rima oris into its esophagus. Think of the esophagus every bit a long H2O slide that extends from the rima oris all the way downward the neck, emptying into the crop. Food remains inward the crop until it moves into the breadbasket (proventriculus).
WHAT’S NORMAL
It helps to know how a normal crop should experience when learning to position crop problems. To examine a chicken’s crop, pick it upward amongst its tail facing yous together with nib facing away from you, (think: hug from behind/Heimlich maneuver) together with thence gain about to the front end of its breast, slightly to the correct of center. If yous can’t experience anything, either the crop is empty or you’re inward the incorrect spot- commonly also high upward on the neck.
Normal, total crop
An empty crop stimulates a chicken’s appetite together with a total crop is the signal to a aeroplane to halt eating. The capacity of a normal crop is roughly 1.5 oz (45cc), thence a chicken eats inward pocket-sized increments oft throughout the day. After eating, the crop feels swollen together with slightly firm, but shrinks every bit nutrient is digested.
NORMAL: the crop can’t hold out felt when it’s empty.
NORMAL: the crop feels swollen, total afterward having eaten.
NORMAL: the crop feels to a greater extent than swollen than usual, but swelling goes downward overnight.
ABNORMAL: the crop feels difficult together with the swelling does non conk downward overnight. This could signal a crop impaction, which way nutrient or other fibrous cloth such every bit straw is stuck inward the crop.
ABNORMAL: crop feels squishy together with the chicken’s breath smells bad or sour. Sour crop, also known every bit thrush, crop mycosis or a yeast infection caused past times a fungus.
ABNORMAL: the crop feels large together with saggy or H2O balloon-like. Contents of the crop exercise non empty regularly. The crop is visibly distended together with soft.

WHAT IS PENDULOUS CROP?
A normal crop expands when nutrient together with H2O are ingested; its contents are together with thence moved into the side past times side department of the digestive tract together with the crop shrinks dorsum to its resting size. An abnormal crop that has lost its powerfulness to shrink dorsum to its resting size is known every bit a pendulous crop. H5N1 pendulous crop doesn't empty fully, which oft results inward infections, almost commonly yeast (aka: sour crop/thrush/candida). The inability to digest properly causes dehydration, malnutrition, weight loss together with ultimately, death. (see video, higher upward and HERE)
CAUSES OF PENDULOUS CROP
- Genetics is a widely suspected motility of pendulous crop inward chickens that are fed regularly, but nobody knows for sure.
- Advanced historic current may hold out a predisposing factor.
- Binge-eating may hold out a contributing factor, if non the cause.
- Nerve impairment associated amongst the crop has been implicated every bit a possible cause

PENDULOUS CROP PREVENTION
- Don't breed chickens amongst pendulous crops
- Provide regular access to clean water together with fresh feed to avoid overzealous gorging
- Monitor crop size together with contents periodically, specially inward heavily feathered breeds whose feathers may obscure bulging crops
Obviously, if a vet watch is an option, consult amongst a vet.

sour crop (treatment described here). The back upward garment may exercise a welcoming surroundings for lice together with mites, thence the aeroplane should hold out checked regularly for parasites. H5N1 crop bra or sling volition non assistance inward all cases.
Once pendulous crop is identified, the chicken's weight, feed together with H2O intake together with droppings should hold out monitored closely. If the chicken loses weight or eyes acquire sunken, it is dehydrated together with malnourished together with it's fourth dimension to consider end of life options.
