My sister has a strong dislike of chickens and all birds..She was 5 and was wearing her cute little 'cowgirl' outfit...with little rhinestone and sparkly bits attached on the outfit. She fell in the chicken house and was swarmed by the birds trying to pickout the shinny bits on her shirt and pants.
She never cared for birds or chicken after that.
The grandparents chicken house was a barn sized structure devoted entirely to chickens that roamed about on the floor space and had roosts along the walls. A couple of hundred of them...we aren't talking back yard stuff here. Almost commercial scale--and they did barter eggs and such with neighbors for milk, cheese, and vegetables.
