Hello, Last week we lost 6 White Pekin ducks and 8 Buff Orpington chickens in 3 separate nights. Night one we lost the 6 ducks, when I last checked on them about 9pm they were making their way across the yard to go in for the night. Half hour later I went to lock them in and found 4 dead, one seriously wounded (died next morning) and one missing. One of the dead was missing its head and all had bite marks on their necks. I know we have red fox in the area so next night I made sure all the chickens were in our chain link dog kennel which is 6 feet high. Next morning all that could be found of the rooster was his head. I thought at the time something had pulled him through the wire. Okay, next night we lock the hens in the chicken house but the door was a 6 foot high chain link door so we attached a piece of lexan to the bottom 30 inches of the door so nothing could push or pull through. Well next morning I have only one hen left and she is totally stressed. Something had climbed over the 6 foot door I assume a total of 14 times to take 7 chickens out. No bodies etc. just all gone with just a few feathers here and there as a trail for a bit of a ways. This time there were tracks left on the lexan and after a great deal of research online they are fisher tracks. My critters are my hobby and I would love to know what to do here and possibly what I have to do to build a fisher proof cage. Thanks in advance!!!
