I believe I have a worm infestation running through my 1.5 year old flock of laying hens. Most of symptoms of being quiet, shaking neck, gulping in air and squeeking/honking (did not see any gape worms looking down their throats with flashlight) with bubbly, clear mucus poop with barely discernable worms no thicker than a human hair and about ¼ long squirming in the mucus part. This has been going on for 2 days. I have started them on Wazine because it was the wormer I could find most locally. Fortunately, it is extremely hot here and they are gulping it down. No one has injectable ivomec but I can get ivomec eprinex. pour on for beef and dairy cattle (eprinomectin). Would this be a good choice in case these are capillary worms? If so, do I use a needleless syringe to apply some on the back of the neck and rub in? If not, should I hold out and take a chance and order injectable online? I'm afraid of it arriving too late and losing hens. Any help would be greatly appreciated for my girls.
