Our 3 month-old chickens (2 Easter Egg-ers, 1 Silver-Laced Wyandotte and 1 Barred Rock) have had diarrhea for the last month or so. We have tried everything: changing their feed from organic to medicated, giving them yogurt and electrolytes in their water, and most recently-medication (aperol)...
Our ISA Brown hen, Dorothy, has a fungus-like coloring on the right side of her head. The other side is normal-looking, a reddish color. Does anyone know what this is and if so, should we be concerned/how should we treat her?
