You are right – chickens do NOT urinate through their skin. In fact, they don’t sweat either, since they don’t have sweat glands. The by-product of protein metabolism in mammals is urea, which is water soluble and released in the liquid we call urine. In birds, the by-product of protein metabolism is uric acid which is not water soluble.
