Ok...I'm fairly new to chicken keeping...Have a hen who has stopped laying and just generally seems like she's not feeling her best. After reading and reading on this forum have about come to the occlusion that she probably needs to be dewormed (which I've never done) or dusted for lice/mites. Anyway planning on dusting her first since she seems to be scratching quite a bit. Next I've also concluded from suggestions that Safe-Guard for goats would be a pretty good wormer to use and is readily available in my area. My questions are: 1. I've seen so many posts on this but still not sure how to administer. Should I put in her water or put in syringe down her throat? The latter I've never done and need to know how to do this. Want to make sure of dosage and how to adminster. 2. Should I also give to my other 2 hens not in the came coop but do free range together? Any link to a previous post would be fine. And...thank you to anyone who can help me even though this has been brought up many times before. Just so much info available it's overwhelming to me. Thanks again.
