Dani,
Do they use the traditional cord through the nose or halters?
I think a camel might be smart enough to recognize 1 bad thing and then associate that with hands, and people..
Have you tried doing a low hum or low key singing to her?
And here is another thought, you say that she has been treated with kindness, but what is kindness to a camel.
Is it indifference, not being hit, simply being fed, watered and left alone?
Or nice pets, brushing, cooing, given little treats?
I only ask is it seems perhaps, if she has simply been left alone and ignored, except for needed care. She may only see hands
and people as ones who cause her pain.
Then again she just may be a dim bulb.
Just wondering.
