Sealed Brood will not stop you from having laying workers no matter how offten you add it. The only two things that I Know of that will stop workers from laying are as follows: 1. A Queen 2. Open brood. In fact a study was done in the USA about the very thing that you are having trouble with and it was found that the open brood was a stronger deterent to laying workers than was a Queen. Just having the queen in the hive will not discourge laying workers. Very large colonies quite often will have laying workers high up in suppers etc. One other note It has been found that while there are as many methods of raising queens as there are people raising queens. The method that keeps coming up with the best queens is the method that you started with. Raising Queens in a queen right colonie has definite advantages over the queenless methods. In experiments with the method that you are using which is know as a collective colonies TARANOV got only 32.2% of his Queens with a weight of over 200mg. Whereas he got 51.7 percent over 200 mg in queenright coloines. It is an accepted fact that the heaver a queen the larger number of ovaries that she contains. ( a drop in weight of 10 mg can have the net result of 40 ovaries) queens with weights of 200 mg. have been shown to have an avarge of 330 ovaries. Before I start a flame session on the bee-L about queen rearing methods, let me also state the following. The method that you use is far less important than the condition of the colonie and its capacity to nurse the queen cells, Queen less or Queen right each of the methods will produce good queens. In regards to you question about laying workers. I have no good news to give you it is one of the pitfalls of that type of Queen rearing. Most of the operations that use that method, use the colonies 30 days and then start over. There is a method close to the one you are using that will enable you to raise queens in a queen less Colony see Steve Tabers book Breeding Super Bees. He has a method which works well.
