Note 733 — Chapter LVI · DISEASES OF THE FEET[731] THE “PINNE”[732] IN THE FEET
D. C. (Douglas Craven) Phillott translation
“Bating” on a hard perch during the moult when the hawk is heavy, will also cause this disease. Also a hard perch when the pressure always falls on the same spot, will produce it. Hawks moulted on sand do not suffer from it.
