So I have a hen that is looking poorly. She is hunched up with feathers ruffled, pale comb, sleeping a lot and not eating or drinking much. She is also "gapeing". No other respiratory symptoms. A lot of my hens have dirty butt fluff. Nothing seen in any of their poop except a different hen had a dark red streak that at first I thought was old blood but now I wonder if it was a gapeworm. After seeing the red streak I put corid in their water thinking it was coccidiosis. After research, I decided to worm my flock. Yesterday, we gave them Valbazen 1/2ml for standards and 1/4ml for bantams. We individually dosed 74 chickens. According to my research, I plan to dose them 3 days in a row total, then again in 10 days for 3 days. Is that correct for gapeworm? Or should I switch to Safeguard? Or use a larger dose of Valbazen? When will I see worms in the poop if they have them? In the meantime, I have been giving the one hen scrambled duck eggs, yogurt and Gatorade. Thanks for your help.
