Negative side effects or danger from long-term use of anti-pick meds?

[backintime]

I've kept Blue-Kote on my hen's bare patches on my hen's back and head for around 3 months now. (Rooster rehomed long ago).

As soon as the Blu-Kote wears off, the other hens peck at her bald head. I'm thinking the feathers won't return til moult. Is there any danger of consuming eggs when a hen needs long-term use of an anti-pick medication?

Does Pick-no-more need less frequent application than Blu-Kote?

I would remove the hen that is doing the pecking for a couple day, then put her back in the flock. She should now be on the bottom of the pecking order.
