Mites help

[Destined2evolve]

We discovered mites a week or two ago and sprayed them down with elector PSP along with the coop, bedding, etc. My question is, egg production has dramatically been impacted so is there anything I can do to help them recover from the mites and stress??

Fresh food and water.
Poultry vitamins a couple of days a week would be o.k.
