During the sunshine today had a first look through the 4 hives with some surprising results. all were fed thymol treated syrup last August and OA gas at the end of December, 3 in wood and 1 poly smiths. one of the wooden hives had 9 full frames brood, I've never seen this at this time of year, with no varroa on the board I checked some drone brood assuming they are in with the brood but still no v. The poly and 1 of the woods with 5 frames of brood, the 3rd with 3 brood all nice patterns.
So, if the queens are well bred and healthy does it really matter what type of hive they're in
