I noticed a week or more ago that one or two has black tar poop. didn't think it was big deal because i gave them a free range block with molasses . now some have watery diarrhea . They are laying and don't act sick. only symptoms is the change in poop . Do i need to worm? (never have) i bought some wazine I feed them medicated chick feed when they were chicks.could it be cocci? I wasn't sure about crop issues? they all seem normal not spongy, full of grain at night..they have been in my flowerbed eating bugs ,maybe ate mulch? I've been searching threads and don't want to give antibiotics if not sick. i added ACV to the water. Please any advice welcome.
