Limited daylight hours in the winter can reduce or stop hens’ egg production, as can cold weather, said Applegate. Improperly stored feed can become compromised and affect egg production, too.
Make sure your houseplants are receiving adequate light in winter before you fertilize them. Plants absorb fertilizer better when they get plenty of light. Watch for signs of overfertilizing.
Egg prices have surged 50% as bird flu forces farmers to cull millions of hens. Alex Simpson, the President of Simpson Eggs, says farmer efforts aren't enough—and he's pushing for urgent action.
Before this, chickens did not thrive during the winter due to lack of sunlight, and egg production, incubation, and meat production in the off-season were all very difficult, making poultry a seasonal and expensive proposition. Year-round production lowered costs, especially for broilers. Artificial daylight supplementation also started being used.
However, a further study conducted by the German government concluded that embryos do not feel pain before day 13, and the law was adjusted accordingly. This was a positive development for the in-ovo sexing industry, since many technologies can work before day 13, but not before day 7.
A common practice among hatcheries for egg-laying hens is the culling of newly hatched male chicks since they do not lay eggs and do not grow fast enough to be profitable for meat. There are plans to more ethically destroy the eggs before the chicks are hatched, using "in-ovo" sex determination.
Trader Joe’s describes their fertile eggs as ones that were “laid by hens in contact with roosters.” That doesn’t necessarily mean every egg in the carton can hatch. That doesn’t ...

Delayed-feathering in chickens is a genetically determined delay in the first weeks of feather growing, which occurs normally among the chicks of many chicken breeds and no longer manifests itself once the chicken completes adult plumage.
