I treated my hen for Gapeworm on Saturday using 2 drops orally of ivermectin. Could have been a slight improvement yesterday but today she's back to sounding just as bad. The weather turned cold again, but I don't think that is a factor. I originally thought this was respiratory, but after 7 days of antibiotics and no improvement I'm relatively sure I'm dealing with gapeworm. We have the perfect environment. My question is: I want to treat her today with Safeguard. I'm thinking about doing the 3-5 day treatment in the water. But I'm concerned that it's too soon since I just gave her ivermectin on Saturday. Does anyone know if this is dangerous, and if I should just stick out the 10 days before trying the safeguard????
