We open the coop every morning....Everyone comes down the ramp and starts their day! This am one of the roosters didn't come down....he remained in the coop all day...We checked on him and picked him up and checked him over....No apparent injuries eyes appear clear...no runny nose....he is usually the one to watch out for the girls....seemed to be head man....could he have been dethroned and was pouting all day?? He is a 5 month old silkie...All of them are silkies....1 frizzle....3 roos....5 hens...
