I try to give my buck and 1 wethers a dose of Ammonium Cloride , a drench about every 6 weeks. I do 2 drenched a week apart. Do you think this if ok or should I do more or less. So far I’m having no problems doing this. I use bath tub water troughs do adding to water is out. I use a 50ml drench gun and give 2 tablespoons mixed in gun at 25ml to each one, then a week later repeat.
