An object with red and blue flashing lights, hovered over my house, then flew off.

Before going to bed, I went outside to close the chicken coop. I turned to go back to the house and looked up at the stars in the clear sky. Above my house, about 750-1,000 ft. in the air I saw a circular object hovering. The object had one red light on the side and a blue/green light directly opposite. Both lights were flashing simultaneously. I immediately ruled out this object as a helicopter, because there was no noise whatsoever. I assumed that this object was a drone. I wondered why a drone would be flying over my house and who would be flying it. I wondered if the police operated drones and then realized that in any case this would have to be.a very large drone. If my estimation of its altitude is correct, the object may have been about 10-15 ft. in diameter. Aside from the flashing lights being visible, I could also make out the vague circular shape which was lighter than the night sky. After about 30 seconds of staring a the object, suddenly the lights went out. The object was still there. I could still see it hovering with no movement. It remained there without lights for about another 5 seconds, then it began a slow widening arc. I watched it curve slowly West, South and then as drifted to the Southeast it blended into the night sky. I waited for it to return or for the lights to appear again, but nothing happened, so I went inside. The attached image is an image of my house which I photoshopped to make it look like night and to show the relative size and where the object appeared.
At this time of night I had not yet gone to bed, was not dreaming, or experiencing any kind of hallucination. I don't drink or do any kind of drugs that would cause any kind of artificial experience.
