I am growing fast and looking for some advice from other side-liners and commercial beekeepers. Feeders... Buckets/extra supers take up too much space and are always back at the shop when I need them, glass jars break to easy, and hive top feeders take up to much space and are expensive. What do you all running a few hundred colonies to thousands use? What are your thoughts on frame feeders? My thoughts are to keep them in the hive 12 months out of the year (I feed in the spring, summer dearth, and fall) and always have access to them when I need them where I need them. I currently do not own a single one so I am looking for any tips, suggestions, or comments about the use of them or how you efficiently feed your colonies.
