This is my first season as a beek and started a Langstroth Hive with plastic foundation and a package of bees. The bees have drawn their comb pretty evenly except on one frame they've done something that seems odd to me. Most of the frame is drawn normally except about 1/3 of it protrudes greatly and it appears the bees have tunnels that go between the back of the comb and the plastic foundation. The first time they did this I caught it early and removed that section of comb. But they built it the same way. I don't want to keep removing it if they're going to keep doing it like that and waist their resources when I'd rather them be drawling out new comb on frames not yet complete. I'd appreciate any feedback and can add photos next weekend but I'm out of town at the moment.
