I install my packages tomorrow. I'll be using foundationless frames but at one point someone convinced me to use a few Mann Lake plastic foundation frames so the bees have something to climb up. My foundationless frames Kelley F style with the wood triangle comb guide. I was also going to direct release the queen on these plastic foundation frames (but only use 2 per box). My hives are perfectly level. Should I just introduce the package with all only foundationless frames or leave a couple of plastic frames in there too?
