Sounds like your hives look exactly like mine. I went into mine a couple weeks ago and sure seemed like I was seeing a lot of drone cells. What scared me was that I didn't see any brood to speak of. I talked with Mark Gretchen and he mentioned that I might have a laying worker since I never saw a queen(like that's something new, me being able to find a queen).
I am going to keep a close eye on the hive and I have a queen ordered, just in case. This would be her third year so I was going to re-queen anyway.
Hope the weather straightens up soon. Too darn cold and windy to be in the hives for a few days.
