Stunted feathers after worming?

[LaurelRidgeDreams]

Has anyone experienced stunted feather growth after worming with Panacur/Safeguard/Fenbendazole?

I've heard that it's possible and you shouldn't use the febendazole wormers during a molt for that reason, but I don't have personal experience with it.

I've read the same thing. My pullets are 16 weeks old and are working on their adult feathers, I think. I plan to worm them with Panacur next week. Just wondering what kind of feather damage that might cause.

In your situation I would wait if possible. At 16 weeks they aren't likely to be overloaded with worms and chickens, like most animals, can handle a low wormload just fine. I worm once a year in November, after my girls molt, since that seems to be the time of year when my egg count is lowest. Saves me from having to throw out too many eggs.
You might ask speckledhen about it. I know there are some wormers that don't affect feather growth, but can't recall which ones right now.
