My two year old Amber Star ,Truffle, is behaving very oddly. She had sour crop a month ago which I treated successfully with yogurt but then laid several lumps of very weird stuff which I discovered was called lash. She's not laid anything since but has been fine and behaving normally. Yesterday she didn't come to the morning feed as usual so I picked her up to check her crop but that was empty. She felt quite heavy in my arms which is unusual and, apart from the odd bit of greens and some mealworms I gave her she's off her food completely. Her comb is a bit floppy but still a reasonable red and her eyes are bright. She doesn't wander and scratch about like the other two but spends most of her time sitting down fluffed up. Can anyone offer any advice please, I am puzzled and concerned but can't afford a vet!!
