You all make excellent points. My kennel cage does need better, more permanent predator-proofing in areas. But the only thing that has kept me from really making it a safe, solid permanent enclosure is the fact that we won't be living here next year. By then, we'll have to be living in a property that we own (paying a mortgage on). Currently, we live in a home owned by my father. My logic with the chicken wire was that it's inexpensive and easy enough for me to cut along the bottom & corners of the cage for when it is time to move & take the kennel down. Once its set back up again, I do plan on putting the money into hardware cloth. All the upgrades can be designed to be easily moved. I have some wire laying on the ground attached to one of my gates. Every time I want to open the gate I just fold up the ground wire, attach the free edge to the gate with some latches (like you'd see on a dog leash), and then when I'm done with the gate I just unclip the latches and lay the wire back down. You could easily fold up the wire when the chain link panels are moved.. Hardware cloth permanently attaches to the sides, so that is not affected by moving. Also, it's a good idea to have your predator proofing perfect when you move into a new neighborhood. Many new flocks get killed during the first week after a move. Predators are very curious about new things. The rest of the issues are something I can fix now, and I realize that. I guess I have become relxed here due to how easy its been as far as wild varmits & predators go, Where we lived before, back behind a state park, raccoons would routinely break into our trash cans. We even had a bobcat show up once (I didn't have chickens at this time). Here, the worst annoyance has been one of our neighbor's yappy yorkie. He gets tore up any time he sees our cats, which is multiple times daily lol. He's in a fenced in yard btw. And I'm pretty sure if I threw one of our cats over on his side, he'd cry & run (you've met those types of dogs haven't you? lol).
I do plan on making improvements to the roosting area this weekend. Will probably be able to afford a small length of hardware cloth from our local supply store to wrap that area with. If there's lots of different places to buy farm supplies, it can be worth it to call around. When I shopped for my hardware cloth, I found anything from 78cents/foot to $1.08 per foot. As I kept calling around, I eventually found a place that sold it to me for 54 cents/foot if I bought the 100 foot roll. If you have financial concerns, sometimes in the long run it is cheaper to save up for the right (final) product, then to spend money on something that is going to have to be replaced in a short time. As far as aerial predators, chicken hawks & owls would be my only concern. I'll try to work up some kinda bird netting to cover the gap as well. Bird netting can be expensive unless you find it on a super sale. Welded wire can be less expensive, and raccoons can't chew through it. That problem will be drastically improved when I go to buy the correct sized tarp for the top this fall & use the other to cover the backside & roost area. Then I can just come up with something to block off the front & back triangle openings. As temporary barrier against raptors only, you can put an old sheet up to close the openings. Raccoons and opossums won't be impressed, but raptors won't go through it. For a long term barrier you'll need welded wire or hardware cloth. I'm not really sure what to do about the gaps next to the door on either side. If I continue wire, I'm anchoring the door to the walls & I'd be afraid the constant bending would break the wire sooner than later. Any suggestions other than what I'm doing currently with the wooden board? There are several options. Probably the easiest is to attach a width of welded wire (or hardware cloth) to the current wall wire with hog rings or j-clips. The hog rings or j-clips will act as door hinges. Then the other edge of the wire "patch" is attached to the other side of the opening, or perhaps bent to go around a corner. Ideally the patch should have a decent overlap of the chain link. The clips would need to be removed every time you opened the run door, but that would only take seconds if you used multiple clips instead of baling wire. A raccoon is unlikely to open all of them.
As far as a coon lifting the latch & opening the door, You many not can tell, but there's a thick yellow chain also locked in place to keep the door from being opened.
I have to brag on our cats here too btw. They're very good with the chickens. And are actually fascinated & kind to them. They get to see the chicks go from incubator to our bedroom floor in a brooder for 5-6 weeks, all during which time the cats get to look in on them anytime. Then once they go outside, our cats actually all gather to follow me when I go to the coop to feed or let them out or clean. We've never had a problem & actually, when they're free ranging under the bushed & trees along the sides of our house, the cats will hang out wherever they can be right in the middle of the flock. Our dog is our livestock/cat guardian, so she protects the chickens. Our only 2 neighbors with dogs that aren't fenced all day, are small breeds that have never once bothered our chickens or cats. They even come during free range time to watch the commotion. We joke sometimes(neighbors too) that we have a perfect, functional animal community going on of perfectly mannered pets lol.
I'll make what issues secure that I can on my Saturday off this weekend & post pictures next week to see what you all think. I appreciate the honest opinion & advice, really. I've known it could be more secure, but this has done the trick so far here & I've gotten relaxed. But you're right, it's better to be prepared or the worst, than to have to worst happen & lose a whole flock to a rare happening. So true!!
