Question to anyone. I found one of my hives queen and with no brood, not even any drone cells (from laying workers). So I introduced three frames of 1-3 day old brood. Now two weeks later I can only find one queen cell. I always thought they would produce at least a few queen cells? Is this unique?

One more question. I have some Terramycin that is now 3 years old. It has been stored in my shed over the past two winters. Does age or cold New England winters have any effect on it's life span?

        Thanks !
