What is the cause of crooked toes in chickens?
Most crooked toe conditions are either management or nutrition related. A lack of the vitamin riboflavin results in an inward curling of the toes and is called curled toe paralysis. Improper incubation temperatures will increase the incidence of crooked toes as will inbreeding. A few chickens with crooked toes (3-5 per 100) are not unusual. High yield meat-type birds will have more of a problem with crooked toes but this generally does not hurt the birds.
