I have successfully treated my 8 BO hens (17 weeks old) for cocci. No one displayed any symptoms for the disease except for the bloody droppings....no lethargy or strange behavior. Now I'm noticing one girl is gaping (is that what it's called when they open their beaks and stretch their necks?) and shaking her head. I tried to open her beak to have a look inside....wow that is hard to convince a chicken to let you do....and don't see anything abnormal. But then again, I've never looked inside a chickens mouth before. I didn't see anything gross looking She also sneezed on me and I got sprayed with a clear liquid. In addition to that, I've seen some rice-looking particles in some droppings so I'm assuming there are worms in some or all of my girlies. I need advice on how long to wait to treat them for anything after completing a round of Corid. Also, what would you treat for and with what? Should I worm them first (I have Wazine) or treat for the girl with sniffles and head shaking first. What would I use for that? Does anyone have any tips on how to look in a chickens mouth? My girls kept shaking their heads and making it very difficult. Thank you!
