I have a small flock of 5 birds, lately I've been noticing dark colored poops in the run. Is it cocci? They have been free ranging and their first stop is always under the bird feeder. If I treat for coccidosis, will the eggs be safe to eat during treatment? Could it be something else? They all look healthy, active and nice bright combs.
Chickens can get Mareks disease from wild birds and there isn't much you can do to prevent it with free ranging chickens. Yours have probably developed some immunity to it. The dark poo could be your birds should be wormed but, the range of what is ok poo is big. You should not eat eggs for 14 days after worming. http://chat.allotment-garden.org/index.php?topic=17568.0 This is a link to a poop chart.
