I think the original hive swarmed this afternoon. I was called to attend to a swarm just up the road, and they are Carni's like mine. I can't be certain of course, but when I looked in the original hive this PM there is an emerged queen cell. So I've taken decisive action:
1. Removed a frame of brood + one QC to the queenless hive;
2. Taken one QC and placed with a cupful of Bs in an Apidea (bought at the Gloucester auction last weekend);
3. Destroyed all remaining QCs except one unsealed one containing a fat larvae.
Fortunately there is stacks of sealed worker brood.
These Carnis are a bit troublesome aren't they. My other colony of Italian type Bs seem to be much less inclined to swarm - I went through them yesterday and not one QC or even any play cups, and they are currently filling their third super.
