One of my hens has had runny poop for 4-5 days now. I'm not sure if it is something that is happening constantly, or just in some circumstances. However I've been seeing some runny spots out in the run and I saw one come from one chicken. Both girls are eating fine and active, also both are laying. There are also normal droppings to be found as well. I don't really give too many treats and they both just started laying recently. Is this something to be worried about or will it pass?
