Don't know mite count. I'm wondering if they are starving as per KathyP recommended, I've started feeding since the population has dropped dramatically in this hive.
This frame was pulled from a bottom deep near the outside and there were no bees on it. I scraped the top off of one cell to look inside, and I think they may be all dead too. Other frames had some new larvae and some capped brood, but nowhere near this full.
Yesterday was in the 70's, and hive #1 was very active, while this hive had maybe ~20 bees per minute coming and going. I'm worried I'm going to lose them all.
