Ball of light, sometimes flashing red, white, green; sometimes bigger and solid white

Almost nightly, we see a ball of light, sometimes flashing white, green, and red, sometimes larger and closer to the ground, appearing like a bright white light. It's over farm ground, mostly wheat fields and blue grass. It moves accross the sky and seems to disappear/cut the lights at will. It does this when an airplane is crossing it's same area. I've watched that happen multiple times. It's below the clouds. It can move in any direction. I have seen up to three of these in the same sky area at once. It's usually just one though. I've taken poor quality cell phone video of it. I've also tried to take video when it's really moving around and had it disappear from sight before I can get my video rolling. We joke that it must just be the government or an Amazon drone. However, I think it's too big to be a drone. I watch it nightly from our residence. It's almost always off to the west. I've never seen it while the sun's been up.
