Chickens threatened by climate change

What climate change does to chickens…

Not quite as cute or endearing as koalas or polar bears, but still. Needs must when the going gets tough…

Climate change is now affecting chickens. Researchers at Macquarie University have found that higher temperatures could be dangerous for hens.

Parent birds normally lay only one egg a day and control incubation by modifying the temperature that triggers embryo development to produce a clutch of around five chicks that all hatch at the same time.

But according to researchers at the Royal Society of Open Science at Macquarie University, climate change is taking hens control away and causing eggs to hatch earlier.

“If global temperatures were to increase it could play havoc with the family dynamic of these birds, creating situations where a single nest contains chicks from different ages, even causing some embryos to die,” said Professor Simon Griffith.

If one egg hatches before the rest, the first chick will have a monopoly on food. And if temperatures rise above 40.5C researchers say it could be “lethal” for chicks. (source)

I thought it would be a good thing – the eggs would arrive ready-boiled…
