Hello All, Last night about 11:30 we heard our girls making a racket. I went out and checked on them and sure enough there was a snake in the coop. Called my husband and he took the snake out of the coop and killed it. The snake was on the roost post and now my girls won't go on the roost. Can chickens smell? Will I need to wash the roost post off before they get back on? Any suggestions? Thanks for any help you can give me.
