No eggs at all

[greenchicken22]

I have had chickens for about two years now and have never had this happen. I have 25 hens and 5 roosters. Half are a year and a half - two years and the others are 8-12 months old. About 5 months ago the oldest 12 stopped laying. A few went through a moult but are done now. The youngest started laying about two to three months ago and have suddenly stopped. They are Free Range but they have been locked up for the last two weeks so I can see who's laying rouge. Turns out known is laying anything and haven't had one egg with 25 chickens. I have tried everything..!! I wonder if they have a diesease. Please help. I can't afford to keep feeding them without egg production.

Well, the older ones may not start laying again until the days begin to grow longer after Winter Solstice, how long after remains to be seen.
Not sure about your younger ones, tho birds that age can molt their first fall, and they can also be affected by the shorter days.
5 males is a lot, why so many?

Knowing more about your goals for keeping chickens,
your flock size(numbers, ages, genders),
your coop(size in feet by feet with pics),
and what and how exactly you are feeding,
might offer clues to if there is a solvable problem.

I am having the same problem. The birds all seem healthy but little or no eggs produced.
