Dirt separation from cement.

We just had this fence built 5months ago, but have been in a drought and 100 degree weather. The 4x4 are 3 foot down and are loose making the fence move with the wind. We just got rain what should I do to save these post. I’m looking at least 40 of them are loose. Thanks

Dirt has separated due to shrinkage during heat?

Make up a slurry of cement and pour around the existing concrete, something thin enough it will seep down the hole!

Sounds like the posts aren't deep enough and or packed well enough.
As Marq suggested, some watered down concrete should help. Just a couple bags of Portland cement without additional gravel will do.
That being said, I'd be looking at having who ever did the work come back however if the fence is flopping around in the wind. I did hundreds of posts one summer on a buffalo farm, no concrete, and it's still standing.

Do I need to let the ground dry before the cement your saying to pour in?

I would do now with the largest gap, as the soil expands it will only get tighter!
