Re: Queen cells not hatching
If you are in an agricultural area then there are a whole host of suspects. The concentrated nature of royal jelly makes raising queen cells the proverbial "canary in the coal mine". We occassionally see issues like this and we raise them in an area with nothing more than an occassional small garden. First concentrate on the things you have control over. Check very closely for any signs of brood disease, even the tiniest indication of an irregularity might be a clue and you might consider a tm treatment. A good quality pollen supplement also may help if the problem is toxic pollen either from pesticide residue or a source such as Yellow Jasmine. If you have any other hives you can use as builders from a different area I would definitely consider that as well. Best of luck, cell problems can be discouraging. It's a big reason I don't like to install anything younger than a 10 to 11 day old cell. I figure the bees are doing you a favor by spotting and "chewing out" anything that isn't healthy.
