I had a weak colony and wanted to add some more bees to it - so it took 2 frames full of bees and brood and added them to the weak colony using the newspaper method
in just 24hours they merged nicely
but i noticed 1 problem - after merging all the bees went to the lower chamber and left all the brood that i added unattended and potentially this brood died due to the night cold
how can i avoid this in the future?
would it have been better if i just added the brood frames with no bees?
