Ok,
North and south yards are 10 to 12 miles apart.
Apis, I did what you are saying this year. when spring was done I moved about 10 very strong hives to the south yards and looks like at least 4 of them have now swarmed. Ugh That's a lot of work moving them to have them swarm. I was wondering what they would do being so strong then being put on a strong nectar flow. I mean, I know what happens, but it's the time of year I didn't know about.
The 2 that were already south that I removed the queens from in spring are 2 deeps and 3 supers high and stuffed with bees but I saw no signs of swarming Sunday. This is what made me think about leaving them in south yards and removing queens from all of the south hives in spring.
Keep in mind I am still learning but I can tell you, I have raising bees figured out. My problem is keeping them in the boxes.
The advantage is that the south flow is predictable. I know when beans etc are planted and they are all irrigated so not really any guessing involved. Winter wheat gets harvested and then beans are planted.
I will read through your post several more times and digest what you are saying. This is fun though, spend the first 3 or 4 years focusing whats inside the box now the picture gets much much bigger.
