My DH had one "rule" when he said yes to chickens.. That they would not roost/go on the children's playset.. Well.. they are.. they are about 8 weeks old..give or take.. and have free run of the yard during the day with access to their coop and run at all times. Yet I find them roosting on the top part (the fort part) of the playset. I've already been out and scrubbed it clean a few times.. yet they keep going there.. I shoo them away any time they go near or I find them on it.. Is there any way to keep them off the playset.. The part they are on is the fort part, that has a slide and other play things off of it. It is covered with a "Roof" and ncie and cozy.. I'd want to sit there too.. but they really can't. It is about 5 1/2 feet off the ground. help!
