Black chicken?
Is this the latest in genetic engineering to stop Mr Fox seeing it
in the
dark?

How are the chickens laying now it is cold?

They are hardly laying at all.

That's why I asked:-)

Local farmer says, "Neck one with t'others watching. It encourages 'em."

There could be something in that statement?

Unlikely that the ones that arent necked would realise
that the reason one was necked was because they werent
laying enough and so would start laying more.

I read an article a few years back that said, birth rates in countries of
wealth and well being breed less. The opposite showed to be true.

Neither fit the facts.

I have no idea how this effects females but, the sperm of the males are
more active and stronger.

Like hell it is.
