[Jacob-list] sheep faces/ copper deficiency/greying

[SharHill at aol.com]

<If they can remember only 50 sheep faces, how is it that flocks that are 
larger than that seem to have pecking orders that work consistently?>


1.  I read that article when it came out a while ago.  I think it stated that 
sheep can probably recognize more than 50 sheep faces, they just picked that 
number and stopped testing there.  They didn't test for more than 50 faces.

I hope I helped you.

2.  <Copper deficiency in the fleece shows up as a loss of colour 
(to grey) and strength of staple to some extent.>

  There was recent talk about genetic causes of greying in Jacobs.  Are the 
additional symptoms of copper deficiency sufficient to make you think there 
is something wrong with the sheep and do something about it, rather continue 
on your merry way, attributing it to natural greying?  Trisha obviously 
noticed there was something wrong with her sheep and figured out the cause.  
I'm just wondering how easy that is for not very experienced shepherds to 
pick that up.  

Thanks.
