My Silkie rooster fell in the pond. I don't know how long the rooster was in the pond but I found him floating and looking very cold and unable to help himself out of the water. I pulled him out and he was in obvious shock, shivering, not moving and not eating. The rooster (previously untouchable and flighty) allowed me to pick him up and I placed him the coop in the sunshine (it was 71 degrees here in Georgia) and after four hours he was still shivering slightly, but feathers drying. Next morning he was fine, eating and scratching. The problem: My rooster has not crowed since the plunge. Prior to the accident, he started crowing at 4:30 am and crowed on the hour, every hour...all day long. Also the previously persnickety creature now comes up to me every day for a scratch on the back of his neck and annouces his presence by softly rubbing his neck against my leg. Possible brain damage or just a thankful bird? Please advise.
