Help. My two silkies who are now 17 weeks old continue to sleep on the lowest bar in my coop - which is in front of the lowest laying boxes (the bar is really not meant for roosting but more for getting up and into the lower laying boxes - it is quite low to the ground. ) I have to move them EVERY night because they keep getting pooped on. They are sleeping under other birds and their back gets pooped on. gross! I am tired of moving them and really tired of cleaning them up. Anyone have any ideas on how to encourage hens to sleep in a different place?
