I got wormout gel and used today as day one. I used 47ml in a gallon and I’m pretty sure not a single bird drank it. I am going to see how they do tomorrow but I’m sure it will be the same. If they do not drink any, or near enough, am I ok to hit them with some panacur (fenbendazole)? If so, how much do I use of the horse syringe? Average sized hens (isa browns, rhode reds and smallest is an americauna).
