Grief?

Sylvia, the older Soay Ewe died suddenly last week.
I found her laid out by the access gate to the new graveyard. She still had grass in her mouth.
Her end was peaceful.
Since then Irene has seemed lost and vocal. The neighbours, I have noted have rallied around to give her tidbits which she takes pragmatically, but to me she looks more nervous and is calling out for her mother who has been her world since she arrive here in 2011.
I have debated whether to rehome her in a larger flock but after discussion with the Prof now have advertised for a field mate for her...another tame  ewe or castrated ram to keep her company.
In the mean time, I took half an hour out of my morning to sit with her in the field.
She also seems more clingy than normal.
I fed her some oats and carrots and she came up to me for a while and ate before trotting up to the cemetery fencing where she again raised her head over the railings and called into the wind for her mother.
