I have a rooster that I purchased from a reputable breeder and his is a size b serama. He is fully grown and proven fertile before my purchase. He has been with us for about 3 weeks and is now closing his eyes and puffing up his chest during the day. It's as if he doesn't get any sleep at night. He opens his eyes to eat and drink and walks around for a few minutes and then closes his eyes and puffs up his chest. He is not gasping, no foul smell or watery or swollen eyes and appears healthy otherwise. I don't know what to think. Is he depressed?
