Re: B.M. feeder too short
The deeps I purchased are also too short. I glued on a small block on each frame rest ear. A Pain, but I like the feeders... only need remove one frame to use them and they nice thick stiff plastic and hold about three quarts or close to a gallon. The floaters need to be scraped as the mold seams area make it so it rubs and keeps the floater from floating. Quick fix it is with a wood rasp. It's too bad they too short, They must have shorter hives where these are made or something.
20+ years, raise my own queens, feed when needed, I treat but have not perfected varroa management yet.
