You're such a good reference... You're my walking handbook!!!
I haven't properly wormed them before now (used Rooster Booster worming once, though). So I think everyone is due. (Nothing observed in poops.)
As I have Wazine on hand, I will start with that (unless you have other advice?). Much easier to have something that I can put in the water. From the directions, I should put it in the water on one day, and then worm again 30 days later - does this sound right? Unfamiliar territory for me.
Also, as it covers only roundworms, should I also worm with SafeGuard later?
(And the bottle says not to use it in egg laying chickens - you were saying usual withdrawal is two weeks?)
Sorry for all the questions...

Any chance you could have someone do a fecal float and gram stain on the iffy one? That would be best. If roundworm eggs are found, use Wazine, pyrantel or Safeguard. If you can't get a fecal don, might be best to do her with Safeguard orally at 50mg/kg for five consecutive days... that will rule out the worms I listed in a reply to Chickencanoe. Would also be helpful to see a picture of her poops (regular poop and cecal poop).
Wazine - I read somewhere that it has an efficacy of 80%, but I can't remember where I read that. Keep in mind that non laying adults drink ~5% of their body weight per day, laying hens drink ~13% and growing birds drink about ~18% (from Avian Medicine - Principles and Applications), so keep that in mind.
Disclaimer... I haven't used Wazine before, so not sure how I would use it. Think I'd be tempted to give it orally and repeat in 10-14 days.
Does that help at all?
