That sounds promising.
The amprolium won't have had time to do the job. You need to give the ' treatment ' dose for 5-7 days , then halve the dosage for a further 5-7 days , then halve the dosage for another 5-7 days . Effectively you are treating for 3 weeks, by gradually reducing the level of amprolium you are assisting the birds to develop some level of immunity whilst maintaining protection from the Protozoa . This prolonged treatment can cause problems with birds that are already thiamine B1 deficient .
I have heard stories of birds that have had complete recovery from wryneck , so don't despair yet. Most pellet feeds have everything added nowadays but the heat used in the process can deplete some of these vitamins . Storage and used by dates should also be carefully considered. Humidity and moisture will destroy these properties rapidly.
I don't store feed for any longer than 1 month and check all bags for ' use by ' dates.
Now that you have seen a deficiency and once you track down some nutridrench , it's best to routinely add it to the drinking water, especially in times of stress, ie molt, brooding and Ill thrift.
Keep us posted on your little one
Wow, when I researched the Amprolium dosages I always read (using 9.6% liquid) to use 9.5 CCs per gallon for 5-7 days, with only some people recommending following it up for another three days two weeks later. I hadn't read about the 3 week treatment. If that is how it's meant to be done I suspect that is why it came back, as they were only on it 7 days. I still have them on the Corid until I get the sulfadimethoxine in my actual hands because I believe they have a particularly bad case of cocci and am afraid to stop treatment even for a few days.
Tabitha's legs aren't in working order yet, but her head/neck coordination seems even better this morning, and she ate and drank even more than she did at any point yesterday, so I still have hope. She was chattering happily the whole time she was eating. She was not particularly friendly as a small chick but since she's had the wry neck and has needed handled so often she's become very sweet.
I will start checking the use by dates on feed. I only buy one bag at a time so I usually only have it for a few weeks. I keep it it metal bins which seems to help keep out most of the humidity, at least so far.
Good luck with your little breda! She sounds very sweet.
Thank you again for all the help everyone has given.
