New beekeeper here. Zone 8b. I bought these two nucs a month ago from a local beekeeper, fed them both a small jar of 1/1 sugar water, some pollen patty and noticed this last sunday. Went out again tonight to do some weedeating out there and the're still there today. I inspected their hive last sunday and noticed queen cups but none had any eggs that I could see. I plan on going back out this weekend again and giving them a pretty deep inspection again to make sure. I don't have anymore open comb to give them. I am checker boarding the empty frames that are in there. I've definitely watched a million youtube videos about it but am wondering if anyone has anything to add? Thanks for any input.
