Quick update -
Just got back from the vets and he's pleased with how Ri is doing. He said he thinks we're over the worst but it's down to one day at a time really.
If there is any Aspergillosis (or other infection) brought on by shock and stress - then he's having the meds that he would have had for that anyway. He can't do any tests but said the meds should help, just in case. He wants him to take the meds for another week (so that will be about a fortnight for Baytril and Itrafungol and longer for the Metacam). He said any danger to the liver and kidneys, due to taking the meds for longer, is a risk that needs taking for now.
He wasn't too worried about the weight loss and weighed him on his scales and he was the same as he was there last week (though that's after eating loads this morning). I prefer to take the morning weight as the right one and he's lost 4g over the past couple of days on my scales (same time each morning, after morning poo and before food). He said his keel is more prominent because there may be slight muscle wastage, due to him not being able to use his wings as much. He said that may be the cause of the weight loss too.
He asked whether he was pooing ok, as on the x ray, you can see his digestive system has been pushed over slightly. Good job he didn't tell me that last week, I would be checking him every 5 minutes (instead of the current 6 :/ ) . He said there is a concern that, as the spine mends together, that there is no neurological damage.
I mentioned the slight click in his chest and he said that was normal. He said his breathing seemed better than last week - still labored but more so after exertion. He still puts that down to pain. I wish I'd asked him to listen to his chest though - I forgot to do that. It's all really guess work, at the moment, due to not being able to do more tests.
So, carry on with the meds (as long as he doesn't vomit) and I'm back next Monday. I think my mind is a little bit more at ease, knowing that even if there was an infection - he's on the meds that would be used and all is being done that can be. Now it's down to fate/luck, I think.
Now I'll just stress about any more weight loss and whether he's pooing ok, or if the spine healing will pinch a nerve, causing damage somewhere.
A big thank you to everyone - your support and prayers mean the world to us.
