Very lethargic not wanting to eat or drink, other chicks were pecking at its bottom to the point it was bleeding. I have separated from others. Stool was stuck to bottom and I cleaned area. The Cal Ranch store where I bought said to use iodine on site and then place antibiotic ointment. Keep clean and dry, force chick to drink by placing beak in water every couple of hours. Is there anything else I should do?
