I've spent a lot of time thinking about this, as I'm sure you can imagine. Teddy and Neeja have made hardly any progress since they started getting medicine 3 days ago. All the things that I thought were progress ended up not really being much. For instance, I don't think Teddy's crop is actually emptying any faster than it was on Saturday and there was actually a slight change in poop color for a little while last night before it went back to being fluorescent green. They're losing a little more weight every day and the difference between them and Phoenix is so startling. Tomorrow it will be 1 week since I really realized there was a problem- that's half of their lives. There was a problem before that too but I didn't realize what it was. I'm afraid that even if they did somehow manage to survive, they would be very sickly adults too.
Paul and I have decided to give them until Thursday night to make noticeable improvements or we're going to take them to be euthanized on Friday morning. Of course if they make some miracle recovery on Friday morning we would not have them euthanized. Friday will be 6 days of medication.
I decided against returning them to the nest box because they would simply starve and dehydrate to death over the period of a couple days while the yeast and bacterial infections took their toll too. Going to the vet would be the quickest and least painful method for them.
I hope people don't criticize me for this. Believe me, it breaks my heart to think about giving up on them, but I don't want their little lives to be so full of suffering forever. It's even harder because they associate me with food and get very excited when they see me because they're so hungry. Next week I'm going to be out of town for 4 or 5 days (it is unavoidable) and if I did drag out their lives until then, Paul would not be able to give them the round the clock care that I am because he has to go to work. If they have improved by the time I go out of town, they won't need as much care (and will hopefully be back with their parents even) so Paul would be able to handle it.
Phoenix we will be staying with Arthur and Poppet and we'll hope for the best because he appears to be doing okay so far. If he does end up getting sick, there's not much I can do for him because he's already being given the same medications as Teddy and Neeja and parent fed babies do better than hand fed ones anyway.
