I started my flock's first worming-session 9 days ago. They all got Wazine. Tomorrow (10 days after the Wazine) I'm planning to give them all pour-on Eprinex. However, yesterday, Holly decided to start to molt. Can I give her the Eprinex? It seems dumb to worm everybody except Holly, as she'll just give all her worms back to the others. I don't want to over-stress her poor little body either.
