Urates quesion

Boople shed last night and upon inspecting her shed skin she had grey urates. I almost thought she swallowed a river rock. Upon breaking it open it was white on the inside with a grey color. It really did look like a small smooth rounded rock. Is this normal?

Yup....sometimes gray, sometimes white/cream, sometimes yellow, sometimes greenish...all OK.

My Hog routinely has grey urates. No worries.

About the only colors to give me pause would be red or orange.
