I spoke to Paula last night (and took the opportunity to catch up too

). And I know that Margy had already given her sterling advice.
She is doing all the right things. She is trying to give him time to settle in to his new environment, good food, encouragement, toys, aloe spray washes, vitamins, calcium, milk thistle (as per Shaz's regime) and trying some camomile tea to help him relax.
His 'bleeding' is not severe - as Nigel says, a few blood spots where he has plucked on his chest, so no medical emergencies.
Paula's giving him TLC and letting him settle in gently and I'm sure with her love and attention he will settle well. (She has a talent with CAGs.) He is not a BL bird, his owners are considering whether or not to donate him, but I'm sure Paula will keep us all informed.
