Hi all. I just ordere 4 10 week pullets and got in wed. Have coop (pre fab see design) and something tore thru patched fence last night and got into my coop. thinking it got in thru unlocked nest box. I am horrified this happened already. One survived. 2 were gone with only feathers left and one was dead with gash wound on side of body. Not sure thinking a racoon gone in.. I want to secure it right away properly to prevent this from happening again. I was thinking electric wiring around coop for nighttime??? and raccoon trap.. any thoughts??
