so tonight i went to put away our chickens (they like to sit on top of there dog pen instead of going inside it and yes i know they need a coop we've been tight on money and seem to do just fine in the extra large metal Kong dog crate) anyways when i opened the gate to there pen my flashlight ran across what i assumed to be a rat...however when i shined my light on it it turned its face to me and it was a baby opossum. probably not a baby baby but it wasn't an adult. i have a picture of it ill upload. anyways it was already in the wooden coop and i dont know if it realized there were chickens about four feet above its head roosting...thankfully none of the chickens were sleeping in the pen on the floor of the coop. i sprung into action and managed to get ahold of it without it biting me. it didn't put up too much of a struggle. so i left my girls and went to deal with the issue. it was covered in fleas and possible deer ticks so mom put a little front line on it and i released it further up the street into the hills which granted the hills back up to my yard but i figured it was a baby it could have hurt my chickens it didn't. tho i do think it helped itself to eggs. usually we get about 15-20 the past two days 20 and then 24 eggs. today it was 10. usually i collect em in the day time about half way threw the day but today got busy so i did it at night. anyways if it comes back ill be forced to end its life as its either my chickens or it. so my question is...HOW DO I PREVENT THEM/ALL PREDITORS? the chickens live under a tree and above the tree is telephone and electric lines. so is there anything to prevent like raccoons opossums coyotes and all that? any ideas will be helpful i love all 28 of my baby's. and dont want to loose any. btw i think it got in because some of the staples have fallen out so part of the fence hangs open which I'm fixing tomorrow moring. you know people say tv rots your brain...psh they lie if it wasnt for wild man on animal planet i would have never known how to catch it. i didnt have very protective gloves like him just some everyday gardening/work gloves.
