Yesterday I checked on my hive that made it through the winter. My plan is/was to split this spring. In the mean time I put on a non-drawn foundation deep to have them build up for the honey flow. This hive is on all pierco foundation. Both brood boxes are drawn. I decided when I added the 3rd box to use all wax foundation to see if they would draw it out quickly. It's been 3 weeks now and they have not touched it one bit. So, I decided to remove and replace with Pierco foundation. Anyone ever had this problem? Also, when I bought my wax foundations they did not smell like "bees wax" It had more of a chemical/bees wax smell. Every time I've bought Pierco it smells wonderful.
