Chickens going into nesting boxes but not laying

[Mother of Chaos]

Ok, I always give them access to oyster shell, how often should I give them the other supplements

For the protein, one small serving a day, several days a week. For instance, I divide up a pound of ground beef into a cheapo silicon ice cube tray, one that I can twist out the frozen ground beef. So I might serve one frozen (and thawed) blob per chicken twice a week. Them maybe sardines or canned tuna or scrambled eggs another 2-3 times a week.

I would tailor this (serving more, or serving less) according to how the egglaying reacted, or didn’t.

There’s a lot of playing around involved with this sort of thing.
