Noticed the runt (hopper size but should be bigger) in my colony walking funny the other day. It would almost move both rear legs together. This morning it was lying on its side and barely struggled when I scooped it up. In my hands it would try to roll clockwise and forward instead of walking. Anybody have an idea what could cause this? Haven't used any chemicals recently in the apartment. The only change to their habitat since Jan-05 has been a drop in feeder.
