I'm planning on switching to small cell size in the spring. Replacing the old comb 5.4 with with mann lake PF120 small cell. I think it might be easier since there will be a time when no brood and very little honey is in the hive.
1. Switching it all at once might cause them to leave. Checker board half then trade out the other half?
Or wait till they have frames of brood and add a frame at a time in the middle of the brood.
2. Once they build up the new PF120 will they be the right size or will I have to replace those too?
