Upon inspection, without even so much as a fortifying coffee, I did indeed find a rather large scrub python curled up and sleeping off a big feed of one of the chooks. This is something I find quite irritating.
So we gathered up a large sack, some baling twine to tie it shut and the camera. I then hauled the now quite indignant python out of the chook shed and we bagged him up before a long trip down the road. All up he was a little over four metres long. Not quite as big as the last one I saw hereabouts but certainly large enough to be a nuisance.
I released him in a large stand of rainforest about twenty kilometres away where I hope he will settle in and not try to get home.
