With those breeds and at 11 months I’d expect you to see some eggs, even at this time of year. Some chickens will wait until the days get longer to start but your queens and reds should be laying by now. If you are south of the equator, they really should be laying by now. It is strange that you have not seen any eggs at all. It might help some if we knew roughly where you are.
A very common cause of you not getting eggs is that they are hiding the nests. That’s my first guess. Another possible cause is that something is eating them.
Many egg eaters will leave signs behind, and many egg eaters are not that consistent. They may get all or most of the eggs some days but there are usually days that they don’t get all of them, if any.
A rat, possum, or skunk should eat eggs right there. A raccoon might carry eggs away for a short distance to a safer spot but you should fine egg shells. If the chickens are eating the eggs themselves, they often leave some shells but you should at least find a soggy spot in the nest. Not all predators read the same book and they don’t always act the way they should, but that is about all you have to go on.
Snakes can eat eggs without leaving a trace, but they normally eat whatever they can hold then stay away for a few days until they digest what they got.
Canines are very capable of eating the eggs without a trace but most of the time a fox or coyote will be more interested in meat than eggs. They probably won’t get them all either.
A dog may fit the bill, though. They don’t always go after the chickens. Do you have a pet dog that has learned the egg song is an invitation to a snack?
A human can take eggs without leaving a trace. Could a person get all of them without you seeing them? Kind of creepy to think about, I know.
What I suggest if you can is to lock them up until they lay eggs where you can find them, if they are laying. That may mean they cannot get to a hidden nest or that you have locked out a predator, but at least you will know if they are laying.
It is always possible they are just not laying yet, strange as that may seem. If you look at their vents you can get a pretty good idea if they are laying or at least fixing to. A large moist soft vent means they are probably laying or getting ready to. A small hard tight vent means they are not laying.
Good luck. These things can be difficult and are certainly frustrating.
