About a month ago, a predator got my hen when she snuck outside of the chicken yard. Then about 1 1/2 weeks later, got my roo, inside of the chicken yard. Both during the middle of the day. I know it had to be the same predator, because both chickens were left intact, except there necks were stripped down to the trachea, with their heads barely hanging on. After alot of research, we determined it is a good chance it was a mink, since we do have them out here, and most anything else would of either taken the body or at least done more damage. Anyway, I have had a live trap out for about 2 1/2 weeks now. Nothing. First, I used tuna, then I switched to chicken livers, making sure to have lots of the blood with it. Twice, the bait has been stolen, but that is because the stupid trap froze! I lubed up all the moving parts with vasoline, and rebaited. That was a little over a week ago. Still nothing. The bait hasn't been touched either. My chickens are kept in a 10' x 40' fully enclosed run while I'm in and out. I only let them freerange while I am able to supervise. If I am going to be gone for a very long time, they stay in the coop. I know as soon as I allow them to freerange all day again, that darn mink is going to return. How long should I keep trying to live trap? I know most will say "till I get something" but I'm just wondering if there is a point that you just kind of give up? I know that 2 1/2 weeks isn't very long, but how long do most of you try for? Thanks!
