My 25, 3 week old Cornish X are healthy but their chunky butt catches the poo and there is for lack of a better description, poop streaked down the behind but not at all near the vent. I clean the shavings out 2xday... they never did paste up...but their is a pouch of flesh protruding that kinda catches it. So far I have not handled them much only in the beginning to check for pasting up....do I need to wash them off? Not going to lie I am hoping you say no...but I will if I need to. They are pooing fine in abundance almost projectile....they are quite the little beasts. We had an unexpected heat wave and they are not fully feathered I can not wait till I can move them out of my garage brooder into a barn stall... please advice and thanks in advance.
