I got some gorgeous yellow Modena pigeons and kept them in quarantine and one died today with worms coming out of it's mouth. I found her dead that way. So I need to treat them all plus my own flock. I put diatomaceous earth on the food. Should I use just that or wormer also? Should I wait on the wormer to see if they start pooping these worms some first? I don't want to over kill and kill my birds. Please help me save what is left. They are gorgeous birds and I wanted to produce the yellow. I still have a yellow male and yellow argent female. But that is it. Thank you. ps, ten years experience breeding green cheek conures and raising chickens but rather new to Pigeons.
