Title: Hens can choose which sperm fertilises their eggs!!
Post by: Womble on September 07, 2011, 04:33:15 pm

Did anybody else catch this story on the BBC news website (http://www.bbc.co.uk/news/science-environment-14804164)?

It seems that hens can 'eject' the sperm of lower ranking cockerels after mating, to maximise the chances of their eggs being fertilised by the top fella!   What's more, it seems that low ranking cockerels produce more semen in order to compensate.

And all this, from the humble chicken!   The mind boggles!!  :o

Whales do that too - a certain type of whale (can't remember which) has a gang bang and only the semen from the top whale survives.

Well!  I've been called some thing in my time but .....................
This morning I was a 'stubborn wumman'  for refusing to go back downhill to the cars at a mountainous field trial when I was almost at the point of needing the resuscitator ;D  I was told (affectionately I think) to go home and steep my legs in cauld mince ........  or was it my head?
