Will I Get Eggs Today???

I was sitting out on my back patio this morning talking to my mom and I kept hearing this whoosh noise. I thought it was coming from inside the house. Well it wasn't, it was coming from the field beside my house, just out of eyesight.  When I walked out to the yard I saw...

The chickens were going nuts.  They kept running to their house, in and out and squawking, running into each other.  The people in the baskets were waving, unaware of the commotion below.  The girls really didn't like this disruption to their normal, quiet routine.  I hope this commotion won't hold them back from their laying.  They have been so good lately giving me from 3-6 eggs a day.  I'm keeping my fingers crossed.  Just beyond the line of trees in the background is the Willamette River.  They need to get their lift so they can clear the treeline.  Then they like to follow the river, which is about 80 below the bottom of the treeline.  They all made it.  I hope they don't do this on a regular basis.  The chickens will loose all their feather and quit laying if they feel a threat.  I don't know this for real, but they are really sensitive.
