I installed a package 2 days ago & occasionally I'll see one or 2 bees crawling around on the ground. They look fine, but act disoriented & climb to the top of grass & fall off. I tried putting a spoon of sugar water in front of one, but she didn't drink it. I tried putting one on the ledge near the opening of the hive & she fell off. Their wings look fine. Is this normal or is this an unhealthy package?
