Day old chicks or pullets (chickens reaching point-of-lay) are sold by the breeders to farms to commence their lives as commercial layers. By the early 2000s, the industry was changing rapidly in Australia, and ‘free-range’ eggs now constitute over half the eggs on the shelves. However...

While she mentioned the struggle, she forgot to include one important detail: during that terrible rainstorm, we tragically lost many of our turkeys. As any poultry farmer knows, turkeys are especially vulnerable in harsh weather conditions...
Finally, if you’re looking for an easier way to let poultry have their fun and do a little pest-control work while they’re at it, put them aroundyour raised beds. Once my greens are fully established, the chickens don’t want much to do with them. They will, however, scurry around...

Are your hens getting enough? Laying hens need more calcium in their diet to produce eggs since most of an egg’s shell consists of calcium carbonate. Layers ration contains about 3% calcium, and this is usually sufficient for most pullets. However, if you dilute a laying hens diet with ...
After conventional rearing, 996 pullets were placed in 12 large (41,296 cm2; 55 hens/FC) or 12 small (20,880 cm2; 28 hens/FC) FC at week 15. Each FC had two nests, one with a plastic mesh surface and one with a smooth plastic surface (3368 cm2). Half of the FC had both...
