I went out to the coop this morning to find my 16week old roo laying on the ground! He can barely lift his or stand. His stool is runny and yellow! It got down to 29 degrees last night and the coop did get farely cold. I gave him sugar water, and warm scrambled eggs. I put him in a small cage away from everyone and put a heat lamp on him. I'm scared! I don't know what to do!
