And I don't mean just moving over, they completely quit the usual roosting place tonight and moved. In my flock of (now) 41 birds, seven of my young pullets have always roosted on the front ledge of the top row of nesting buckets. Always the same seven, always in the same order, always in the same spot. Tonight, nada. They moved to one of the lower roosting bars away from the rack of nesting buckets. Hmmmm...... methinks I may have a snake in the coop??? I hope he gets one of those nine golf balls I've got in the buckets, and chokes to death. I may dismantle the area tomorrow to ferret him/her out!
