Noticed some red worms in a white watery discharge today--in November I wormed everyone with Eprinex pour on--all the birds look well, a few are molting. Everyone's comb is red and everyone is eating---Because of the dogs in the neighborhood I have to keep my birds in large chain link areas. Grass is now gone and when it rains heavily there is a lot of mud, except in the chicken coops. I scoop and drain the muddy water after each rainfall--the ground gets mushy pretty easily. I do my best... and am still getting eggs. What kind of worms are these and how can I figure out who has the worms? Should I worm everyone again? I do have some ivermectin injectable--should I use an eye dropper and measure out some orally for each one? I also have Wazine but I am thinking this is gapeworm--no one is gasping, etc. Any ideas?
