Nice to see Veg - heads up though on your next inspection make sure that pollen clogged frames are not restricting the brood nest expansion. I had to re-arrange frames in 2 of my colonies for that reason
Its on a double brood so I can split them when the time is right. The reason I put the entrance reducer in that way is so that over winter the entrance doesnt get blocked up with dead bees. They dont seem to struggle to clear them out when the weather is warm enough.
