Odd behavior with a storm, normal?

[drpurl]

I live in WI and the last two days we had very strange weather. We had thundersnow/rain/sleet/snow and when I went to check on the chickens last night two didn't go into the enclosed roost/nesting area. I had to physically put them in. I got my chickens May 1st and this is their first winter. Is this normal?

Yes it is within normal behavior. A scare can cause them to change benavior or do somethinmg different.
