This may only prove that the queen in the small colony can lay a good amount of eggs once she got the work force, but it does not prove that the queen have any other good traits. It's the donor colonies workers who are doing the job and it is of her you may breed!
Guys, in the real world colonies coming through winter will be at different strengths. You can wait watch and see what happens or be proactive and boost those that need help. Nothing to do with queen rearing just basic beekeeping skills.
Some seem to spend all their time pontificating!!!
