UFO Sighting in Georgia on July 4th 2015 – Several orange/red/yellow spheres all heading linearly behind each other about 100 yards apart then changed directions and took off

After shooting off some fireworks around 9 several people and I were in the backyard eating and talking and noticed there was several orange yellow spheres passing through the sky. We thought at first they were just some fireworks or drones or something like that, however they were moving very slowly. We watched several pass and then began to take more notice as they kept coming along the same path. They would all head in one direction slowly then take off in the next direction. About 12-16 passed through this same path. They would take off past our line of sight due to trees being in the way. The movements were very linear and the directional changes sharp. Since it changed speeds and directions so quickly we couldn't figure out what it was. We all had time to take a couple videos and such, but since it was dark it literally looks like a couple small orbs in the sky. In person they looked much larger.
