OK we have 5 chickens that live in a small chicken tractor and free range during the day in the backyard. It's a mixed flock, we've had for about 4 months and they were adults when we got them: 2 Brahmans, one Welsummer, etc. Sorry this is a gross picture - it's the tray in the morning, they had pooped on it and then walked on it. Mostly they seem healthy and most of the poops are normal and healthy. However at least 1 has diahrea...don't know which one it is. Also, what should we do about these worms? What kind of worm is this? We started adding apple cider vinegar to their water - 1T/gal...also added some minced garlic to their food... Will I need to buy some de-wormer? If so, where can this be purchased?
