Deworming has helped our hen immensely! I am seeing an improvement after about 2 days of dewormer. I am giving each hen 0.23 ml of safeguard equine paste once a day (from this article) I haven’t figured out the best way to give it to them. My current strategy is to hide it in a small pile of mealworms. Not sure that’s the best way.You can do it! Just takes practice, patience, and a firm hand!
I think we're going to worm our hen, I just ordered Safeguard (you can find lots of threads here on it). Maybe the worms are causing the crop issue, since she's been on ACS for 7 days now and symptoms are not improving, we'll try this out.
Good luck to you, hope things arrive quick enough to help.
Here’s my thread (if you want to compare notes)…
