At the time of my first predator attack I had been keeping chickens and ducks for 6 years. Thought everything was under control and there were no problems. I had gotten comfortable and neglected some much needed upkeep and improvements. First raccoon attack came from the front of the barn and the buggar pretty much pushed straight through the 'chicken wire'. It tried to take one of my EE hens that miraculously survived but I didn't find her for two days- and she was really tore up. (Thankfully she recovered and lived for another 2 years afterward, but was never the same.) I didn't find Fiona (EE #1) and was clueless about the hole in the wire until the next night when the raccoon came back and this time succeeded in killing and eating my other sweet EE hen INSIDE of the barn. After that I moved all the birds to a secure area and proceeded to trap the assailants. It took 3 nights and I finally got TWO raccoons using marshmellows and what was left of the EE hen(bless her). One had been very well fed I'm assuming on the cat food my grandma left out every night. I swear it weighed 25 pounds. The other was a little smaller, but still huge compared to the squirrel sized trap it managed to squeeze itself into. When I began the barn security renovations I found another place up where the roof eaves met the walls they had been using as an entrance.
My advice: you can not be too secure and never become complacent. Predators will eventually come calling at some point or another. ALWAYS use heavy duty welded wire with SMALL openings, NOT 'chicken wire'. I prefer hardware cloth. Bring pet food in at night and secure your garbage cans. I read an article in Backyard Poultry today that said when it comes to predators, the best offence is a good defense.
