What Animal Has A Hard Thick Egg Shell
1.) Pale-shelled Eggs
The degree of dark-brown color in the egg trounce is determined past the quality of deposited pigment in the cuticle.
Causes:
- Infectious bronchitis
- Bird age (older hen)
- Loftier stress in the flock
- Egg Drib Syndrome 76
- Use of chemotherapeutic
agents (i.e. sulfonamides
and nicarbazin)
2.) Lilac Eggs/Pink Eggs
The egg appears to be pinkish or lilac due to the clan between the cuticle and an actress calcium layer.
Causes:
- Stress
- Excess calcium in the feed
3.) Dirty Eggs
If the egg shell is stained by feces, information technology is important to avoid feed ingredients which cause wet and sticky droppings.
Causes:
- Wet droppings
- Large amounts of
indigestible compounds in
the feed
- Poor gut health
- Electrolyte imbalance/
saline water
iv.) Blood Stained Eggs
Usually from pullets in early lay, eggs are contaminated by smears of claret from a prolapsed cloaca, vent pecking, or cannibalism.
Causes:
- Overweight pullets
- Pullets coming into lay
- Sudden, large increases in day length
- Poor hygiene: Cage, trays,
belt selection-up system
5.) Shell-less Eggs
Laid without a shell layer, these eggs are protected only by the beat out membrane.
Causes:
- Immature trounce gland
- Illness: Avian Influenza
NDV, infectious bronchitis,
Egg Drop Syndrome 76
- Inadequate diet:
Calcium, phosphorus,
manganese, or vitamin D3
vi.) Soft-shelled Eggs
Laid with an incomplete crush, just a thin layer of calcium is deposited on the trounce membrane.
Causes:
- Excessive phosphorus
consumption
- Heat stress
- Bird age (older hen)
- Saline water
- Mycotoxins
7.) Cracks
This problem includes hair line cracks, star cracks, or large cracks that effect in a hole in the shell.
Causes:
- Oestrus stress
- Saline water
- Bird historic period (older hen)
- Inadequate nutrition:
Calcium and vitamin D3
- Mycotoxins
8.) Corrugated Eggs
Characterized by a very rough, corrugated surface, these eggs are produced when plumping is not controlled and terminated.
Causes:
- Heat stress
- Saline water
- Bird age (older hen)
- Poor nutrition, especially
calcium and vitamin D3
- Mycotoxins
ix.) Wrinkled Eggs
Eggs with thinly creased and wrinkled surfaces.
Causes:
- Stress
- Infectious bronchitis
- Defective vanquish gland
- Overcrowding
10.) Pimpled Eggs
Classified by small lumps of calcified fabric on the egg trounce, the severity of pimples depends on the foreign material present during the calcification process.
Causes:
- Bird age
- Strain of bird
- Inadequate diet
11.) Calcium Coated Eggs
An extra layer of calcium can be seen all over the egg or on just one end.
Causes:
- Defective shell gland
- Disturbances during
calcification
- Excess calcium in the diet
12.) Calcium Deposits
These eggs are classified by white, irregularly shaped spots deposited on the external surface of the shell.
Causes:
- Defective shell gland
- Disturbances during
calcification
- Excess calcium in the diet
13 / 14.) White/Brown Speckled
With smaller speckles than calcium deposits, these eggs may be laid down before or after the cuticle is formed.
Causes:
- Defective shell gland
- Disturbances during
calcification
- Excess calcium in the nutrition
fifteen.) Mottled Shells
When placed in front end of a light, the translucent areas appear mottled or glassy as a consequence of the shell's failure to dry quickly.
Causes:
- High humidity in the shed
- Affliction and mycotoxins
- Manganese deficiency
- Overcrowding
sixteen.) Body-Checked Eggs
The egg is croaky in the trounce gland pouch and and so repaired before lay.
Causes:
- Incorrect lighting
- Stress
- Bird age (older hen)
- Overcrowding
17.) Broken and Mended
A diagonal break occurs during germination and is mended once more earlier lay.
Causes:
- Stress during calcification
18.) Misshapen Eggs
These eggs are as well modest or large, round instead of oval, or differ from normal shapes.
Causes:
- Immature shell gland
- Illness: Avian Flu
NDV, infectious bronchitis,
Egg Drop Syndrome 76
- Stress
- Overcrowding
nineteen.) White Banded Eggs
If two eggs come into contact with each other in the beat out gland pouch, normal calcification is interrupted. The commencement egg retained in the pouch will have an extra layer of calcium seen as the white band mark.
Causes:
- Stress
- Changes in lighting
twenty.) Slab-sided Eggs
The second egg that enters the shell gland pouch is not as consummate as the beginning egg and is flattened where the eggs made contact.
Causes:
- Stress
- Changes in lighting
- Affliction
