I have a one week old SLW chick that started looking ill last night. I’ve moved it to a separate brooder with food and water. It made it through the night (with some checks and encouragement to drink!) but I am worried. It keeps chirping, walking to a corner and seems unsteady. Stools appear normal. It is keeping one of its eyes closed but I can’t see any discharge or injury. We are in England. Any idea what is wrong with this little one and what else I can do to help it? Thank you!
