General suggestions.
1. Layer feed is full of calcium in amounts unsafe for roosters. Get him off that completely. Get a chick grower food not starter. Oyster shell on the side for hens, NEVER mixed into their food.
2. Get them a proper water dispenser they can't spill. Or find a way they can't spill that bowl. Not having water all the time can contribute to gout.
3. No salty human food ever. This can also contribute to gout.
4. They should have access to their food all day. Being hungry causes problems.
5. Scratch feed alone will cause other problems. You know that.
So grower all day and fix the water.
