Environmental
Pro's:
They are chickens without feathers or scales
Created at the Hebrew University in Israel by Professor Avigdor Cahaner
Scientists breed a naturally bare neck with a regular broiler chicken.
Mutated with FGF20 (fibroblast growth factor 20)
Scaleless (
sc/sc
) chickens carry a single recessive mutation
sc
trait is located on chromosome 4
Show that a nonsense mutation in FGF20 is associated with the sc/sc phenotype
has cell survival activities and have a variety of biological processes
includes embroyonic development, cell growth, morphogenesis, tissue repair, tumor growth and invasion.
Also used for people with parkinsons disease

Chickens grow faster, energy it takes to grow feathers is put towards growth
Lower in calories and fat (not as much sweat)
Cheaper (no plucking and less AC needed)
Con's
More susceptible to parasites
More susceptible to mosquito attacks
More susceptible to sunburns
May find chickens are unable to mate
More susceptible to injuries
Con's
Less jobs for people
Chickens are not pleasent to the eye
Pro's
Enviornmentally friendly (less feather waste)
Less food is needed
Are able to survive in warm temperatures

Pro's
Healthier meat for people to eat
Pro's
Con's
Con's:
Pro's:
Con's:
Unlikely to be able to adapt to cold temperatures
Cut costs
Don't need to pay for AC
Chickens don't need as much food
Don't have to pay to pluck chickens
Chickens grow faster
Chicken's meat is healthier than regular broiler chickens, meaning could probably sell meat for more money
Low survival rate
Too expensive to be commonly used
Are able to survive in warmer climates
Don't sweat as much
we couldnt find anything on this topic because it is a newer development and still being tested and researched on.
Bibliography
Environment/Society:
Chickens might not be able to adapt to colder temperatures causing death
More susceptible to diseases and injuries
Male chickens may be unable to "woo" female chickens; this my casue a temporary shaortage in chickens
Long-Term:
Risks:
Greater chance of chickens getting disease and transmitting them to humans
Benefits:
Chickens can now survive in warmer temperatures
Will cost less to maintain chickens e.g. people in proverty will be able to take care of their chickens better because it costs less to maintain them
