Hi there! I’ve noticed one of my chickens, whenever she drinks water, she coughs a bit back up along with a fair bit of saliva and also has a bit of dribble down her chin most days. She’s also smells a little stinky. (Probably weird but) I normally like the smell of my chickens, they remind me of wet dog but she smells almost greasy lately? Hard to explain but thought I should mention just in case. Other than that she’s generally a healthy and happy girl! I just adore her so wanted to check what this could potentially be. Thanks!
