The weather is gorgeous. Put your bees out. Best to carry them to their spot. Set them down. Open them up about two hours later. The bees will be pouring out of the open entrance right away. Best to open them up in the afternoon when it is warmer and they can fly and return.
When package bees come to me, there is always loose bees on the outside of many of the cages. We collect them when it is cool and put them in a nuc box. If it is warm out when the bees come, we cannot collect them because they fly away.
I took one of the nuc boxes outside last night, because it needed a queen. I couldn't open it up in my garage as the bees would have poured out in the garage. When I opened them up outside, fifteen minutes later, the bees poured out of the nuc. They settled down a short time later and I put the queen in. It was cooler out last night and I know some of the bees did not return. So releasing them when it is in the upper 50's should be warm enough for them to return.
