Hello all, I hope you have all had a good Christmas. My husband has very kindly bought me 2 WBC hives for Christmas, he bought them because they looked nicer than nationals They came ready assembled with a bag containing 2 porter bee escapes and 2 entrance sliders each, which I understand. In the bag was also a length of wood 1 x 7/8ths x 18 ¾ inch and I have no idea what it is for, can any one help me please. I?m sure it is really simple but it is driving me bonkers! Thanks, Vanessa Hughes
