The Denagard will arrive either today or tomorrow. I feel my hens are in a more susceptible situation to get sick because they’d been sick. 2 are on Tylan for CRD. I have also seen behavior that could be signs of gape worm. Stretching the neck and gaping. Doing this for several times - but then the next day and days after that not doing it at all. It would be only 1 or 2 hens at a time. Then the next day they wouldn’t do it at all but another few hens would. I gave each the ivermectin drops on the back of the neck Saturday. Tuesday will be 10 days. I treated them with ivermectin once about 2 months ago but didn’t not follow up with a retreat. I did not see any signs of worms or mites and lice but understand now that I should have retreated anyway. I have read that ivermectin works great and also that it’s only really effective for mites and lice (I’ve checked them repeatedly and do not see any signs of either and I want to keep it that way!). So I ordered the Denagard. I also ordered yesterday Valbazen (I do not have a projected arrival time for that yet). So what is the best action to take? Give the ivermectin again on Tuesday? Give the Denagard on Tuesday? Give the Denagard as soon as I get it today or tomorrow? Wait for the valbazen? I’m most concerned about the possibility of gape worms, even though if they had it wouldn’t they gape all the time/every day and not just one day a dozen times? This behavior is working it’s way thru the flock. Thanks for helping!
