i went to check my 4 hives but i found no brood i found the queens but on brood Help
If you're in the northern US or Canada chances are the queens have gone idle for the winter. As you just found out No Brood doesn't always mean no queen. If they had lots of stores I wouldn't worry about them until spring. If they lack stores I feed when the weathe permits it to improve their chances of surviving the winter.
As you can see, your location means the answer you get as be more precise to your seasonal conditions.
