I was cleaning sanitizing and repairs coop the other day and found two things.. one I believe they are darkling beetle eggs.. fresh and the only ones found were under a part of the roost that fits and nailed to the floor of coop Then I found dark spots on the wall of coop mostly above nest boxes and on the unpainted part of my coop. It was dry some was clumped some not and most washed or with the water. I scratched some and it powdered off it did have a brownish look to it maybe like dried blood. It was concentrated on the side they all huddle up at there wS also a huge section over that same area of wall that water was leaking. same picture only closer I didnt see any plump red bubbles for red mites in other obvious place they would hide but I had just climbed out of coop talking to hubby and felt a sting looking down was a red fat bellied looking bug it was as big as the end of a used pencil lead. It had two or three legs on each side.. could been a spider because I have lots of webs already all in my coop. I smacked it and smeared red on my arm.. before thinking I could have got a picture. Any thoughts?
