Or you can add lighting to your coop. Hens need 14 to 16 hours continuous light to lay well and keep laying well. They slow down, but will continue to lay at 12 hours of daylight, then become vary sporadic, except for the production breeds (like the RIR) when light drops below 12 hours.
You would need to start the lighting program now (actually in August) to keep their light steady without receiving any production drop. If the lights go out too early, even one night, you will likely see a production drop and can even force a molt.
As ronott1 said, you live at a latitude where you will receive a bit more light than us northern folks, so the slowing will be lessened.
I have had mixed results with the production birds the first year. Some begin laying and lay well for 18 months, then molt, then lay again. Some molt the first fall and don't lay until spring. For me it has to do with when I hatch the chicks. I find chicks that mature by June and are laying well will lay throughout the first fall. If I have them just come into lay in the fall, they often will slow during the winter. If they have not come into lay by fall, then they will not do so until spring. It has to do with how much daylight is needed to trigger the hormones in the brain so that the egg duct matures enough (actually the ovary) in a young pullet to trigger laying. The big boys will even manipulate their lighting system so that pullets do not mature and begin to lay before 16 weeks, targeting around 22 to 24 weeks.
Your Rhodie will likely be a good production girl. Your EE's, well if they've been like mine, not so much so. But EE's vary a lot as they are hybrids. You will not see the production in the EE's however as you will in the RIR. If you want really good egg laying for those first 18 months, then purchase Production Reds or the Sexlinks and have them come into solid lay by June, July latest. Then stagger your broods such that you have pullets maturing for first year lay as your older birds are entering their first fall molt, which in my experience has been from 12 to 18 months. But be prepared some years, especially in my changeable Oregon weather, everyone will be triggered into a molt with an odd change in weather from hot to cold and you may not see eggs for awhile no matter what you do unless you use indoor facilities with lighting.
I prefer to use natural lighting due the hassle and expense of adding proper lighting to the coop. I tried a rechargeable battery system using battery powered LED closet lamps, with success, but a lot of hassle. So electrical money went to kid's college and I try to stagger my birds such that I always have pullets in first year of lay alongside the 2nd year gals, and I cull or re-home at 3 years, except for a couple of sweethearts who have graduated to "pet" status. You can usually easily give away 2 to 2 1/2 year old birds for free on Craigslit or your church list or some community forum.
