So we have runner ducks and Guinea hens and we feed them during the day. We put the food inside the enclosed, (outside the coop) run but leave the main door open because they free range, coming back to coop to eat and check in. This has worked well so they know where Home is and lay their eggs consistently inside. We want the birds protected while eating, from predatory birds...We put the food away at night. The rats are out of control now. I used to catch one here and there in the have a heart traps but then I would have to relocate the darn things and thats not cool, giving another place rat problems...so I bought 3 new rat-kill-traps and bam the first night caught 2, second night, caught one.....then Nothing! I have cleaned the traps, letting the traps air out, etc thinking they smell "death" on them and thats why they won't go near them, but no matter the bait, we get nothing (except the occasional small wild bird or squirrel using the no-kill traps). I have put peanut butter, bacon grease, even sausage, pepperoni...but Nothing! They won't go near the traps! They know they can get a free meal going to the bird feeder! I went and bought brand new traps and the guys at the hardware store laughed at me, saying they reuse their traps till the springs are falling off. Just with baiting a little pepperoni. I tried it! Nothing! what the heck. I sometimes change it up and put the birdfeeder outside the coop but then squirrels get to it. and its open to hawks, etc flying over.... Rats rats rats! I think its the bait?! Why are they not attracted to most any bait anymore?? thanks!
