My whole flock is sneezing and has lice. At night they all make wheezing sounds. One standard chicken has yellow diarrhea. Our bantam silkies have bubbly eyes and one has swelling under one eye. We've bathed them all and cleaned and sanitized coops. We feed them organic food and they free range. Id love an organic approach but more than anything I just want them better. Make it go away!!! Poor babies! Any suggestions???
