So, on with the gloves and into the shed she went, where she was humanely despatched. Not an easy to do operation as we have had her since last August, she was until a few months ago a good layer, then she started pecking her own eggs, not the other twos, just her own. Then she stopped laying completely.
I had hoped that we would leave her until next years laying season to see how she got on, sadly that wasn't to be.
Now we have had to follow the correct way to dispose of the remains, just popping her in the bin isn't the way to do it, so a two foot hole and some lime is the way we went.
The other two are happily laying still, just as they did last winter, all the way through as well.
