I lost 4 Showgirl chicks out of the brooder last night. The brooder is 4' high x4' deep x8' long there is no top on it since it is in the chicken shed. I have never had a silkie or showgirl chick get out of it in the year since it was built. It has solid plywood walls and tongue and groove floor, nice solid little unit. So i was a little shocked when i had 4 missing chicks. I found 2 of them dead out side the barn and the other 2 are Missing in action. So tonight i thought i would go down and do some night time hunting. when i walked into the silkie/showgirl barn a large rat was beeting cheeks for the door and ran right over the top of my foot. So i came in the house got a nice rat trap and set it using peanut butter and bread. I went back down set the trap came back in for an hour before i went back out to check and had a nice fat female rat. well got to get back to the rat killing.
