They are chickens. That's what they do. Relax. The only other question I have that might have a bearing on what you are seeing is this: How old is that feed? If it's old, or rancid, that might be a possible issue. If it's fairly fresh, not an issue. let them eat bugs.But they act like they are starving every time i walk out the door they are rushing towards me for food. I Just worry about their well being they are more like pets than a food source. Of course none of them have a name except for the rooster LOL
