I have 3 hives with a feral or 2 hives coming in the Spring. This Spring 2012 I want to move from 1 deep and 2 mediums into 2 deeps. When do I give them the new deep with wax foundation? Early Spring before thay explode? Where should I put it; bottom, top? This will also give me 6 fully drawn medium supers for honey if needed and it works out.
