I don't speak Spanish, so I hope the computer translator I used worked. I'm not sure what nutrients might be missing, if this is a dietary issue. There is a whole section on the eXtension site (https://articles.extension.org/poultry) on feeds and feeding. They might be helpful. This article is specifically on feeding for egg production: https://articles.extension.org/pages/69065/feeding-chickens-for-egg-production
Lights are also important - hens on short days (12 hours or less of light per day) often won't lay well.
Otherwise, it's difficult to know why they might not be laying.
Sorry I'm not more helpful.
