Hi (I'm new here) My 3 ~6wk old chicks all developed this today. I did feed them organic chick starter (didnt switch brands, same as allways). They've had nothing else other than free range in the garden (no bad plants). It almost looks like a tumor, located upper right shoulder with chest also semi enlarged. Firm to the touch and not hot. Am trying to upload photo - can I email it to someone else to post?
