3 odd lights one 1 very large craft moving in a way aircraft do not.

My husband was out feeding our bottle calf Moomoo when he called me on my cell and said to grab my coat and come look at something quick. I went out and saw a craft that was too large and flying too low and moving in a manner in a way that aircraft do not. It had 3 lights along it the one In the center was steady while the other two blinked, the craft moved slowly and seemed to be rotating as it went. As it moved the center light began to blink as well. It had an aura or outline and you could see it was one large craft not 3 separate ones. We have aircraft that fly over from our small local airport often so we are well acquainted with what they look like at all times of day. This was not normal. As it moved dogs in the areas it moved over began to bark. Also a normal aircraft was in the sky as well and was very clearly different. We watched for several minutes and I went inside.
