Thanks Tofu.
My birds have been out in the coop since early May, and so far, I still have all of them. The biggest hazard they face may actually be the fact that we live on a busy road, not that the predator hazard isn't also a worry. Over the weekend the ducks did try to cross the road, (they almost got all the way to the middle) but luckily a car spooked them. I have 18 birds, (6 ducks, and 12 chickens), so we can lose some and still get eggs.
The ducks and chickens share the coop. I keep the water outside the coop and that helps keep the mess under control. If i have to leave town overnight, I put some water inside and boy they make a mess right quick. But a couple days to dry out and a few added shavings brings it back under control.
My biggest annoyance is that the ducks love to wander. They leave the coop immediately, go to the kiddie pool to grab a drink, and disappear. I have a bunch of neighbors, and no fence surrounding my property, so I worry they'll do some damage to someone's lawn or garden and I'll get in trouble.
One neighbor already complained to the town, but I think I straightened it out with him. I knocked on doors looking for anyone who had an issue, and the first door I tried admitted to calling it in. Turns out, he was angry about a phone call I made a year ago about a stray cat that was languishing on my lawn. It's face had been mauled by some animal, and it was definitely dying. I didn't want to touch it, so I tried to call animal control. I had no idea who's cat it was, turns out it was his. Instead of animal control the town sent a cop. Which I thought was weird. Cop knocked on doors looking for an owner, but the cat had disappeared by then. Apparently the guy thought I had called in an animal cruelty accusation against him. Nope. I explained I just wanted the cat removed as it was in bad shape, and I was worried about rabies, etc. Turns out, the cat died in my garage. Scared the crap out of me when I found it.
But yeah, he'd been mad at me for a year and I had no idea. I'm going to make an effort to be more friendly with him, try and build a bridge.
He told me he actually liked the birds, and I promised him some eggs. And we started getting eggs last week, so the turn-around on the promise should be pretty quick.
I should also go further up the road to look for neighbors who're wondering where these ducks and chickens are coming from. And promise them eggs too.
