Long story short- free range hens, out all day, in coop at night - last four or five days, Cochin hen, Miss Lily, acting listless, not running over for treats, etc. Smelly, poopy butt, some weight loss. Washed her butt, cut out the poo encrusted feathers, called local chicken expert (also person who gave her to me). Saw her yesterday; says she is also a little dehydrated, suspects cocci (apparently common here in fall and early spring). Gave me Sulmet to put in water. (eight hens, only one other acting a little off). Bottle says not to eat the eggs if you give to poultry. So the question is - how long after I stop putting it in the water should I be throwing out the eggs ? Bottle says for meat birds wait 10 days before slaughter. Is is ten days for eggs ? I currently have only one hen that lays, anyways- four teenagers, and three slackers, so it's not like I'd be wasting a lot of eggs- also, could I give these egg, cooked, back to the chickens (or would this just elongate the cycle ?) I have had chickens only since April, and they have not been sick before, so I want to take care of them right- please help !
