Using pour on Ivermectin

[tuner06]

i have duck that seems to have gape worm I gave her pour on ivermectin 2 weeks ago. I was also using vet Rx to cover repertory. she is back to shacking her head but not gaping should I give her the ivermectin again. she also has a little cough. not sure where to go.


Thanks all
Have a great day.
