u/True-Structure-1702

2nd year, western WA, US. I did a walk away split a week ago. I'm feeding the split inside the upper box. The brood chamber is pretty well full of bees but no foraging activity yet. I checked the feed level this morning and spilled a little sugar water outside, next thing I know half a dozen ladies from next door are checking every crack and crevice looking for a way in. Are these robber scouts? I would have assumed they were from this hive except for the lack of activity so far.
