This is my first hive and it went queenless within the last two weeks,have'nt detected laying workers as yet,I have ordered a new queen.My question is what is the should I say safest way to introduce this new queen.Should I place her in the main hive ,or should I use a nuc and screenboard to introduce her?I have no brood to keep worker bees in the nuc with her if I use this method, would it be acceptable to provide them with food/water and close the entance.Thanks in advance
