UPDATE 9/1/11: New pen addition

2x2 framing cut to size and built into two door frames. Place on on each side of the hole and screw together. Mount your door and call it done.

 

Cut a chicken door size hole, frame it with wood (preferably all weather) and install a lockable doggy door or a guillotine style door and a pull rope.

 

Bryan, you can't cut holes in chainlink like that (and have it STAY chainlink), you would need to install stretcher bars on either side of where you make the hole (BEFORE you make the hole!!!) and then finish the cut ends of the wires by bending them back to lock them (which requires heavy duty pliers etc and a fair bit of strength, if it is useful-gauge chainlink). What you describe does work on normal welded/woven wire fencing.

Pawsplus -- are these pre-framed kennel panels (probably)? If so, by far the easiest thing is to detach one corner, pivot one of the panels out til you have a wide enough gap for a doorway, then build a doorway and door out of wood/wire/whatever-you-please and secure it very tightly in that gap. Yeah, you end up with not-exactly-square pens, but hey

Good luck, have fun,

Pat

 

I have made panels to serve as gates for traps out of chain link. I suspect that the same process would work for cutting a hole as well. To build the panels, I used regular chain link stretcher bars (the flat ones) as the outer frame. I had to be careful to set them up so the frame was a bit bigger than the square of chain link I was going to use. In my case, I was making panels about 2' by 3' and 3' by 4'. The smaller one had to be cut down and the cut ends folded down to make it the size I wanted. Then I'd lay it out on a table or flat surface, and gustimate the proper lengths for the 4 stretchers so they overlapped at the ends. Then I drilled holes through these overlaps to accept some small bolts. Then it is a matter of slipping the bars into the fencing, and STRETCHING it to keep it taut. You will probably need some help. I'm here to tell you it is tough to do with only 2 hands. But it CAN be done. In your case, it would be a matter of doing the opposite, frame the hole itself. Were I to do it, I would start by fitting my frame into the uncut fence and once the corners were attached, THEN I'd cut out the center. (when you fit it, be sure to not trap the wire from the cutout under the bars so when you pull them out, you don't lose any of the tightness you have worked so hard to conserve.) For the door, you might consider sizing your hole for a pet door or make one. I do not know how pretty it needs to be, or how light/heavy it needs to be. These things would probably dictate what you use. I wish you luck and suggest you get a good pair of gloves before you begin.
Hope this stirs your imagination a bit.

 

If you are looking for something lightweight and inexpensive, try 1" Schedule 40 PVC pipe. Easy to work with and very light. It just so happens to have the same outside diameter as regular fence posts so all the hardware fits the same way.

You can see it here in this photo.

 

You can remove a section of chain link. There is no need to cut it off.

 

I have a chainlink "gate" or two. Just drive a T-post where you want the "hinge" to be, wire the chainlink tight to the T-post so the whole wall doesn't fall down when you loosen it, then dis-assemble the chainlink on the other side to make an opening (no need to cut it, just take out one of the wires). Peel/roll the chainlink to one side for entry, then "zip" it back up with spring clips (bolt snap clips, carbiners, etc.) Obviously this isn't 100% predator proof, but it works fine to separate two sections of a run when the chickens are locked up at night.
