About an hour ago my less than week old cochin peep, I bought them at a feed store so I'm not sure of the exact age, started scratching at both sides of his head and peeping loudly. He is drinking, eating and eliminating just fine but he can't seem to rest very well since he is constantly scratching at his head. I have looked at him and can see no outward signs of trouble. I have even managed to get him to open his beak and can see no obstructions there. I would appreciate any advice. These are the first peeps I've tried to raise in 35 years and am a nervous wreck!
