i noticed today that i think it might be 1 of the roosters doing it that there are some piles of black runny looking poop. it's not smelling at all so i'm still not sure if it would be cecal poop and i'm not sure if a rooster would do cecal poop. well all our chickens go in and our of their coop into the run area freely. we have the run area fenced in so they only have a designated area to go in. we feed all the chickens right now layers crumbles and soldier worms. a couple days ago, we thru some spinach and lettuce in with the chickens as an extra treat for them. everything looked fine that day and even the next day. they still get some that fall thru the rabbit cage, but in small pieces as well as carrots. this black runny poop didn't show up till today. they have access to grass and dirt all the time. my husband was thinking it's from the heat. everyone looks fine and is acting normal. it's been really hot for us for a few days now.
