Stalactite, Stalagmite?

Ah, it's just an ice cycle. But in the chicken run? I didn't notice them until I knocked one down with my head.

The big one was really interesting. You could see the hexagon indentations of the chicken wire.

Winter Rainbow

That is what I thought it was until the news this evening.  It is actually a sun dog.  There was one on either side of the sun just as it came up.  By the time I got my camera, they were fading.  They are caused by the sunlight being refracted through ice crystals at about a 20 degree angle.
