I split my hive on Monday, one box with the queen and 4-5 drawn frames with honey and pollen, and the other with lots of eggs larvae and brood. Based on the information in ABC-XYZ and a link from MB I am going to check for queen cells in ten days. Then I am going to split the ten frames left into two five frame nucs and let them build up again. Is there any specific criteria for selecting queen cells-- biggest? Thanks.
