Thank you for your reply. I ended up closing the coop at 5pm last night & waited till 9am to open it & give them the wormer. So they went 16 hrs without food & I'm waiting 3 hrs to feed them just in case. I've never done this before and oh my goodness it was crazy!
I put the wormer inside small pieces of bread. 4 of the 20 would not eat it... two of them roosters, so I ended up putting a glob inside their beaks. Needless to say, I had this stuff all over me. If it obsorbs through skin I will consider myself wormed
I haven't seen any worms. I was told to worm them every 6 months for their health.
Am I supposed to do this again in 10 days even if I haven't seen any worms?
