I can only answer from my point of view. I keep 20 laying hens at any one time. Bob down the road has 40 and Jeff his neighbor keeps 6. I know this is very specific information so if this does not answer your question, perhaps joining a local 4H club might help.
Layers or Hens.
No, not all hens cackle while laying.
because its a chubnub.
No. they can if they have a rooster though
They shouldn't effect the process of laying eggs. It's always up to the hens attitude for that day.
No, hens can't be mean. Though they could peck you when you touch them while their laying their egg, but it's not there fault, there only trying to protect their egg. Hens are actually great pets :)
Providing plenty of calcium for the laying hens.
Cold weather does effect a hens laying. when the temperature is below 55 degrees or so this can effect a hens production. Mainly though the reduction in hours of daylight causes hens to stop laying. Anything below 14 hours of daylight will cause a hen to stop laying.
A breed that will lay a brown egg, will not lay a white or tinted egg. However, the eggs will be darker at the begging of hens laying cycle, and can fade to an extremely pale shade by the end of her laying cycle. The only other reason why a hen might lay an unexpected egg color, would be if she was a mix.
Spent hens are poultry that have completed their productive lifespan in the egg-laying process, typically after about 1 to 2 years of laying eggs. These birds are no longer economically viable for egg production, often due to decreased egg output or health issues. As a result, spent hens are usually culled and processed for meat or other uses.
Do you mean, can a rooster lay an egg? The answer is no. Only hens can lay an egg. Do you mean, will a rooster incubate an egg till it hatches? The answer is no, only hens incubate the eggs. Occasionally a rooster that doesn't know any better will sleep in the nestbox but he is not there to incubate and could actually break and eat the egg instead. Do you mean, will a rooster chick hatch out of an egg? Yes, both roosters and hens come from eggs.
Usually, it can take around 2-4 weeks for laying hens to start laying eggs again after being relocated to a new environment. It's important to ensure they have access to proper nutrition, fresh water, and a comfortable coop to help the hens settle in and resume laying.
