We adopted a 3 month old Easter Egger a few days ago from a local shelter. She is quarantined by herself in our bathroom, far away from our current flock. She hasn't shown any other signs of sickness as of yet other than some strange looking stool. No sneezing, coughing, lethargy, etc. We have treated her days before with VetRx under her wings when she first came home as well as MannaPro Pet protector for mites,lice, ticks and fleas. We also added a clove of garlic to her water just in case she had something that could be treated naturally with a natural antibiotic. For the first day we have her on our flock's layer mash and then switched her to a Scratch & Peck for chicks. Forgive me for the picture but does anybody have any idea of what this could be??
