Chicken owning friends.
This document will be of interest.
Note "lifetime withdrawal" means never eat eggs from that hen again because of persisting residue OR lack of information on product in laying hens

Laura Chamberlain Pylan "Fipronil is a pesticide, not a drug, so it is not eligible for extra label use and is not covered by FARAD. It's governed by the EPA. If you scroll to the vet bottom of this link, there is a reference to that from the AVMA. https://www.avma.org/KB/Resources/FAQs/Pages/ELDU-and-AMDUCA-FAQs.aspx. "

Q: Are pesticides subject to ELDU?

A: The use of pesticides by a veterinarian is not subject to ELDU regulations as these are subject to the primary jurisdiction of the Environmental Protection Agency (EPA). Pesticides must always be used according to the instructions on the label.

What the vets are saying is that per farad any pesticide not specifically labeled for poultry is considered extra label use. Extra label use in laying hens of pesticide is unpermitted
But I will ask the vets on the chicken vet group for the specific info for fipronil
Additionally per US regulations Sevin has been banned from the use in laying hens since 2010

Quote: Meaning if the label does not specify poultry it cannot be used on them without "lifetime" withdrawal
But where does is say that? Is that perhaps your interpretation of the law?
