When we say a tank is cycled,it is not the tank or the water, but rather the filter that we wait on to develop a healthy bacterial colony that works to process ammonia created by the fish,and fish foods. Simply moving water from a cycled tank will not mean the new tank is cycled.
What you might consider is placing a small sponge filter in your large tank and let it run 24 /7. Then when you wish to move fish to breeder tank ,or grow out tank,, you would simply need to move the sponge filter from the main tank to the grow out tank and this would produce the biofilter for the tank with fry.
Could also place a small hang on the back filter on your large tank and let it run 24 /7 and when fry tank is needed,simply move the small filter from the large tank to the small tank.
Keep in mind that for sponge filter or small hang on the back filter to be effective,, they will need to run in the cycled aquarium for minimum of four weeks.Could also simply take some filter material from the cycled filter on your large tank and stuff some of the material in a new filter when you place it on the fry tank.
In any event,, water from a cycled aquarium does not provide much in the way of bacteria and it is the filter where the majority of the good bacteria is found.
