They may need a nutrition boost. The bugs are blood suckers the could be anemic from blood loss plus the stress of it. I would try rooster booster or nutrtredence. I hope that helps them. PamI'm still battling the wyandottes with lack of eggs. They quit laying when the gnats came, started back up for a week, then quit again. No gnats or bugs to be seen around the coop. I'm trying a new nest box for them, other than that I'm out of ideas. I hope its not from the heat, otherwise they are in for a long summer.
