I have a hive that I think I'll be able to split in the next couple of weeks, and the hive that I'd like to put them into is only about 4ft away, and oriented in the same direction. I'm curious if this is too close, and if the workers that are heading out to forage will just go back into the original hive? Maybe that's okay?

I do have a nuc that I can put them in first if that would help. Also, not sure if it matters, but these are TBHs, and they do not look the same.
