Chicken

There are now several devices that help you keep food waste out of landfills by converting it to compost … but what if you don't have a garden? Well, the Mill converts such waste into dried grounds which are sent off to feed chickens.

Every day in hen hatcheries around the world, all male chicks are tossed alive into a grinder. A new system could keep those chicks from ever existing, by analyzing the scent of eggs to ascertain the sex of the embryo inside.

You might think that the ol' wood-and-wire chicken coop is one thing that's ineligible for a high-tech makeover. The designers of a camera- and alarm-equipped chicken home known as The Coop, however, would be inclined to disagree.

In the commercial production of apple juice and cider, large quantities of fibrous waste – known as pomace – is generated as a byproduct. And while that material is currently just discarded, new research suggests that it could be used to boost the health of chickens.

The FDA has given California company Upside Foods the green light for its lab-grown chicken, paving the way for it to reach market shelves next year, and making the US the second country in the world to allow legal sales of lab-grown meat products.

A striking study has found eggs from hens in urban backyards can contain up to 40 times more lead than eggs from commercially farmed hens. The researchers recommend those in inner-city locations test their soil before raising chickens or growing food.

In a typical poultry processing facility, much of the waste is simply dumped in a landfill or burned. Two new processes, however, make use of the feathers, blood and bones – plus one of them may ironically reduce the number of chickens slaughtered.

Making inroads in the world of lab-grown meats is Israeli startup Future Meats, which has just received the largest investment ever seen in the cultured meat industry and is rapidly reducing the production costs of its cultured chicken.

Chickens have never had a reputation as intellectual heavyweights and scientists may have found the reason why. Experimental breeding suggests the domestication of the chicken 10,00 years ago caused the bird's brain to shrink and made them less fearful.

Last year, we heard how KFC was introducing a plant-based chicken substitute on its menu. Now, the company is going a step further, by looking into bioprinted meat made from lab-grown chicken cells.

Even when they're allowed to roam, chickens are still susceptible to infestations of blood-sucking mites. It now turns out that a backpack-like device could let farmers know when those mites are biting, so treatment could begin as soon as possible.

When it comes to farm animals being raised in subpar conditions, chickens often have it particularly rough. A new system that analyzes chick vocalizations, however, could help alert farmers (or authorities) when things really need to change.
