You may remember from an earlier post that the dominant cockerel chick, Redhead, had started trying to crow and sounded like a Kazoo. You may also remember that one of the other cockerel chicks was also trying to crow but it wasn't as loud.   In addition, you may remember that we took them down to the allotment on Monday, because this dual crowing attempts early in the morning were likely to cause a nuisance?
Well. The chicks are very happy in their new environment. We've put away their garden home and netting,  I've raked up the poo, we've watered the grass and we're attempting to get our "lawn" back.   We miss the chicks, but it's quite pleasant not having Chickenopolis in the back garden any more.
But back to my original point
Turns out it wasn't one of the other cockerel chicks crowing. 
Nope.  One of our lovely ladies has picked it
      up as the "let us out" signal, and she's been deploying it every
      morning before 5 am.   We seem to get a biblical 3 "crows", then
      there is a short interval  while they  give us time to get up, get
      downstairs, unlock the kitchen door, cross the garden and let them
      out.  If we haven't complied within the allotted time-frame,  the
      rest  add their voices one by one, like a chickeny dawn chorus on
      steroids - i.e. with the sweet melody of birdsong replaced by
      harsh rasps and/or sorrowful whingeing (dependant on bird). 
It always amazes me that my chooks pick up habits that suit them immediately, yet habits that don't suit them are almost impossible to ingrain.
