I have an almost 4 month old bantum White Face Black Spanish cockerel. I noticed today that he looked puffed up, tail was down, wattles paler than normal. He was somewhat isolating himself from the rest of the flock but would move pretty quickly if a dominate came near him. He did some foraging with the others and ran for scratch. When I picked him up for inspection, I noticed his abdomn felt swollen, firm but not hard, squishable when pressed. Vent was clean and puckered when touched. butt feathers were clean as well. Watched him poop and it was normal color and consistency. When I was holding he appeared to be kind of gasping to breathe but he was not doing this standing on his own. No signs of any other birds acting sick. Any suggestions for home treatment are appreciated. Vet is not an option. Thankyou for any suggestions.
