Hey everyone! So I have a 4 week old duckling I rescued a couple of days ago. He was initially broken out of his shell (from a horrid school hatchling project) and since then he has been slower than his siblings with 'squinty' eyes. He was never given veterinary care until now. My vet had him on an IV as he was severely dehydrated (was one of 10) and gave critical care. The IV was taken out 24 hours ago and he continued to eat and drink ok. Today his eyes are still half closed, which he itches when he bathes himself, he is quite lethargic and droops his head forward in what seems to be exhastion, but then stands tall and has a flap and stretch, then back down. My vet is unsure what could be wrong and has put him on a broad spectrum antibiotic, synulox. I've got him on electrolytes, water and his feed. Any suggestions would be greatly appreciated. This is my first duckling and I need help. I will do any test necessary as he is part of the family (not food), he got himself this far, I don't want to give up on him now. Many thanks in advance!
