Pictured is one of my rhode island reds with black lumps on the soles of her feet. She seems to be in some discomfort. She is one 1 and a half years old and part of a flock of 42 birds, who are housed in a secure shed and have access to large area of pasture.
Does anyone know what it is?
How to treat it?
Is it contagious?
How to prevent it in others and in future?
Any advice welcone
