The origins of the word 'poddy' are officially unknown, however what is known is that it is English in origin, and stemmed from the UK around 1890-1895.
In any event, it's an orphaned animal, pertaining especially to lambs.
Sadly, there are times when a ewe will walk away from her baby/babies. This is especially common when the weather is 'drought-y'. The mother is often too weak to support her young, and will, quite literally, walk away from her babies. It's a sad fact of nature, and farmers do their best to make sure it doesn't happen.
Short of destocking, the only real option that will ensure a poddy lamb's survival is to hand rear it. This is a times consuming and expensive option, and can make selling the animal much harder to do at a later date. Poddy lambs are often given names, and become a much loved family pet. Much loved, but also a hidden cost in a drought.
Some farmers do it on a larger scale. Next door to where we live, they are currently caring for 10 poddy lambs. I posted these images on my blog facebook page, but for everyone else, here they are!
Enjoy. Total cuteness!
