Update: she is still gasping for air, she also feels more stiff. She still moves her legs, but barely before she would thrash them.
I gave the antibiotic and the anti-inflammatory. I am also trying to syringe feed her, and I gave her a bit of Nutra drench.
Okay. Anti-inflammatory and antibiotic will still be priority at this stage. Great that you are trying to feed and water her.
Antibiotic: a Pekin duck will be around 9 lbs. It is very important the dosage for chicky is right. It would be great to try and weigh her so we can compare directly and adjust dosage of trimethoprim.
Correct dosage is 14mg per pound of bodyweight every 12 or 24 hours.
If the antibiotic container nowhere says what dosage of trimethoprim is in container, we can guess the correct dosage:
(Chick's weight / pekin duck weight) x 3cc
=> approx dosage.
It may be great to change antibiotic if at all possible. But I understand budget may not support that at this time. It would likely mean vet (and then they could do full investigation).
If she is uncomfortable in sling, (leg thrashing cause?) see how she feels out of it, support with rolled towels. Has she only been gaping since sling? Remove immediately to a supported position of comfort, as sling might be pressing fluid in compartment against lungs. Support with rolled towels. She can be on haunches for now if that is what she prefers.
Further:
Check her body for hot, squishy areas. Does she drip fluid from break in a forward tilt position? (Trying to nail inflammation. Gaping often indicates lung involvement, even peri-pneumal fluid, fluid around lung as inflammation causes fluid to arise in this and any compartment in body).
Stiffness could be a sign of neuromuscular compromise, we suspect then electrolytes-- maintain fluids with electrolytes, please.
Importantly, any other symptoms?
I have:
Major open head wound. She did a little better then--progressed to unstable gait, difficulty standing, mouth breathing with use of accessory muscles, lack of appetite, refusing fluids.
Are there any other symptoms?
