Sorry you all are having rat problems. Just a matter of time b/fore I see some here, but so far, so good. I'm convinced that it's b/c I use FF, and there is never any feed left out at night for the nasty creatures. Got squirrels though. Not sure if they're an issue stealing eggs or not. I was finding eggs in strange places in coop and run, at about the same time I had a squirrel with a ratty tail trapped in the run one day. Tried to give him a dose of lead to no avail. No egg issues since. RE: FF or any feed for that matter: Check your dates, and if you get a bag that they refuse to eat, take it back. I had a bad bag one winter, even though it was fresh. My flock was absolutely not eating it no matter how I served it up. Took it back, exchanged it for a new bag, and they went wild, making up for lost time.
