I have the liquid. I'll start it in the morning, they're all getting ready for bed now. I'll also be heading into town to get wormer. I was just out observing them for awhile. They're all acting normal but their combs look pale to me. They are all laying at this point so I would expect them to be deeper red. I'm going to go ahead and treat the flock. Should I deworm my ducks as well? They're area is separated but I walk through where the ducks are to get to the chickens. They share common areas at different times. Plus I let the chickens into the ducks side of the house to turn their straw.
