high pitch noise coming from hive
Hi all: Some background information.....three weeks ago I split my one hive...took the queen and moved some frames of brood/honey and started a new one. The original hive swarmed twice last weekend (Saturday and Monday). The original hive should have a queen by now but maybe not mated yet? The two swarms seems to be doing ok...one was large the other smaller. The split (with the queen and frames) is doing great. The original hive though seems weak since it has swarmed 2x. It also has a high pitched sound when I put my ear to the hive unlike the others...very distinct. Any idea what that would be?
