Hi all! Brand new to chickens and picked them up locally (about an hour away) this evening. On the way home one of my 6 must have gotten a little nervous and pooped in the box they were all in.... So they got a little messy... Can I wash them off? They're about 4 weeks old I'm told and I don't want to scare them or anything but I don't want them stinky either. Thanks for any help!!
