I have two colonies that I started from nucs a little over 3 weeks ago. I fed them a couple pints of 1:1 syrup to get them started. At the time, the dandelion bloom was on, and there was a ton of pollen going in.
At the 1-week inspection, there was some nice solid patches of brood, a decent ring of pollen, and some nectar / syrup stores.
I've fed intermittently since then, and just inspected a second time. Both colonies are well set for nectar/syrup, but there is a complete lack of visible pollen inside. I was expecting as much as while observing the hive as I saw very few bees bringing in pollen supplies. Furthermore, the brood was quite spotty. I found both queens, but I'm wondering if the bees are cannibalising the eggs and young due to the lack of protein.
Both colonies have expanded from ~2.5 frames of bees up to 5-6 frames of bees, so they've grown a fair bit.
I think we are on the edge of clover starting to bloom here - I'm seeing some blooms on my lawn. However, there isn't a ton of pasture close by.
Should I be thinking about feeding some sort of pollen substitute?
