I have a habit of going out and checking my chicken pens before going to bed . So last nite I went out and seen eyes from a distance , went back in the house and got my trusty 22 , and was able to 2 out of 3 possoms that were around the pens . They havn't been able to get in for a while sense I put concrete under all the doors and gates but I have been seeing digging and tracks . I think I hit the 3rd one but it got away . Over the last year they have gotten about 20 of my birds including 5 BCM's that I had just got , and 8 amerconna that I had hatched here .
