Everything seems to have just gone to hell in the last few weeks! First I had an Easter Egger pooping green/yellow and very lethargic. I started her on Penicillin and kept her in the house one night and she perked right up. Next day my big Brahma hen starts wheezing. I gave her a shot of Penicillin,gave her a misting of oxine overnight, ordered Valbazen at that point and took a fecal sample of everyone to OSU large animal services (had to beg them to do fecal testing the first time last year because "We are a large animal facility" Convinced them that worms are worms regardless. When they were tested a year ago and they were clean. Anyway got the results last night and they found gapeworm and roundworm. They are eating very well, but the brahma is shaking her head a bit. Lab person told me to use ivermectin ,but I'm wondering if I should wait until tommorrow for the Valbazen to arrive. I suspect they might have mites also and tractor supply has the ivermectin and safeguard. What to do? Can I give antibiotic and worm at the same time? Can I use ivermectin and then Valbazen in 10 days? Will that kill those nasty gapeworms or kill my chickens? Advice?
