“Rat cunning.” It’s an expression you hear, but you don’t fully understand until you see them in action.
When we created our chicken run, we ran aviary mesh up the sides of the run, and chicken wire across the top. Old concrete garden edges were dug 30cm into the ground on all sides, locking down the wire.
We thought it would be enough to keep out the rats. Boy were we wrong!
Within a month, rats started tunneling under the fence from the convent next door. They went under the concrete edging, and opened up new holes every night. (It doesn’t help that we back onto the railway line, which is both rat haven and highway.)
While the the chickens themselves were safe in their Fort Knox of chicken coops, the rats were scavenging any feed scattered about by the hens.
So I spent the last few weekends digging up the chicken run, laying down wire, and then cementing in the gaps. A lot of work, but hopefully the chickens should be safe now.
Of course, the wire will rust away in a few years. Had we known what we know now, we’d have bitten the bullet and laid a concrete slab when we created the run.
Still, this should last a while. And maybe when these defenses fail, I’ll be feeling more enthusiastic about laying a slab.
The take-away message: don’t underestimate rats, particularly when you live in the inner-city.
