My mom always used the paprika AFTER the hen was done laying - like just before roasting.Will isolate them from cock and feed back some eggs to get reserves back up. Will also pop them with paprika.

Seriously, I thought it was cayenne pepper. I tried giving them a sprinkle a few times in early spring when production was still slow. It may have worked but nothing scientific. It at least stopped the dog from stealing all the chicken feed on those days. Have you found that paprika gives the hens a laying boost?
