An observation of dermatitis in caged dwarf and normal-sized Single Comb White Leghorn laying hens

Dermatitis was observed on the feet of Single Comb White Leghorn hens. Dermatitis scores and score ranges showed lesions to be predominately on the feet of dwarf compared with normal-sized hens. Statistical analysis by log-linear models showed that the percent incidence was closely related to the strains of hen tested and, to a lesser extent, to the type of ration fed the birds.
