I just got myself confused, lol. Actually I only had enough in the tube for 1 or 2 days of treatment I believe. The rest of the days I used the goat dewormer.When I dewormed my flock of 14 with that same dewormer it was maybe 3/4 of the way gone after doing the 5 day treatment. So yeah probably not enough in there.
Sounds like it would be best to just treat the ones in the same coop.
