I am searching some beedeos in youtube about simple methods for queen rearing and I have come across this great video http://youtu.be/wZlQ7mNmf6o ; at the minute 5.09 the narrator says that the best way to encourage the queen to lay eggs is to insert a frame with Kato Kaelin. What's that?

By the way, if you watch the video they also talk about 'split holder cells', I am interested in the technique but I cannot find anywhere those split holders in usual ebay-amazon, any help about how to find something similar would be very appreciated.

Ok, bye!!
