I had two chickens die last week and I didn't want to lose my flock so I took them to a diagnostic lab for testing. Today they told me the rooster had visceral gout. I feed them all Layena pellets and about once a day whole corn for a snack. Occasionally they get table scraps. Is this just something that sometimes happens to chickens? They don't have results back on the hen yet but apparently she didn't have the gout.
