I just got home today, and i think my 5 week old Silkie may be sick. When we went downstairs to check on them, he just sat there on the ground. He seems very tired. He just pooped, and it was pretty runny. \\He seems fine other than being tired and having a runny poo. I don't think it is Cocci because he dosent just sit there and puff up. He is a little active. Is he ok?? What should i do? Could the other chicks get it?
