Thank you for your response. I didn't think to take a picture yesterday and I cleaned the coop. The photo I attached was from today. All are acting normal so not sure whether to treat or wait.
I'm a new chicken owner and yesterday I noticed some blood in the droppings. This morning no blood but the droppings don't look normal to me. I'm not sure which chicken as they are all eating and acting normal. Me and my girls are so attached to these chickens and we would be devastated to lose...
