Yep, I removed the feed and am now feeding the chickens further out in the yard, on top of my picnic table....then taking the feed back into the house (and leaving no scraps behind!). Haven's seen a rat since doing that, but I'm still planning to set out my electronic trap, which should arrive by UPS tomorrow.
That said....I sure hope I can eventually return to feeding them in the coop. We've had chickens for years and never had a rat problem. Not sure why they suddenly appeared or even where they came from. We live in the burbs and there has been sewer line replacement going on in our neighborhood. My wife thinks the rats live in the sewers and were disturbed enough by this latest maintenance work that some wandering rats picked up on my chicken feed location.
As to poison, I do understand that people use it because it is extremely effective. And if there is a HUGE population, it may be the only way to bring the numbers down to where other methods can control the infestation. But that poison is REALLY effective and seems to have a long shelf life. Even a crumble of it getting dropped about could be a very bad thing. I had an old shed torn down last year and witnessed my hens picking around near the demo site. About an hour later, one of them died a horrible death. The only thing we could figure out is that she had gotten a hold of a pellet or two of old mouse poison. I didn't have any in there, but the shed was old...so a previous home owner may have placed some in there. At any rate...I will avoid rat poison if at all possible.
