My first thoughts are keep here and the others out of the pond. This is most probably where they are picking up the leeches. I think you should also be checking the other ducks as well and any other fowl who may have had contact with this duck or the water. If you can offer a kiddie pool or some such thing so they can bathe and somehow keep them from the grounds surrounding the pond. Not easy, I'm sure.Good News & Bad News on my little Tallullah Belle.
This morning she seemed a lot better on herself, she didn't look as swollen, was stood up and stretching her neck up (seemed like she couldn't stretch up last night)
The dish of water with Epsom Salts was knocked over so I presumed she hadn't drunk much of that. Made some more up for her but she was still stressing this morning and wouldn't drink to start with, so I put her in the sink for a warm epsom salts bath. She did drink some of this but almost immediately snorted out another leech. The leech looked dead as though the salt had worked on it. Good News that the salt worked but bad news that there was one in there, was hoping that they weren't actually inside her. Left her in there for approx. 20 mins and she did keep having big drinks so I've fingers crossed that if there's any more in there the salt has done the same to them.
Her eyes went a little red but think was due to the salt in the water so gave her another soak in fresh water.
Managed to calm her down and watched her drink more epsom salt solution & ate some breakfast.
By then the other ducks were all up, she could her them and started stressing again. She's still a little wobbly on her feet and still keeps falling backwards. So I've let her back out with the others to calm her down and was going to bring her back in tonight and try the salt bath again.
Oh and first poo after the salt bath did look a little like yolk!!
All of the other ducks have had their morning swim and are now on the side of the pond preening themselves. As she keeps falling over when she tries to stand on one foot and scratch with the other, she's stayed in the water but seems to be managing to scratch and preen herself.
Will keep a eye on her throughout the day.
Should I have kept her inside for the day even though she's stressing out - as she's not 100% at the moment didn't want her picking up any more leeches by putting her out but couldn't see her stressing all day??
Isn't it hard to know what to do for the best, (big sigh)
Another thing to think about...if this is also a case of peritonitis, an antibiotic may be needed. You will need to watch this bird very carefully to see how she is progressing. If the stomach doesn't go back to normal size soon, I would highly reccoment a dosing of either Sulmet or Di-Methox. Whichever you can get. The Sulmet is a bit more harsh than the Di-Methox, but then so again is the peritonitis. The reason I am suggesting either of these is to kick the infection back and also to kill and purge any remaining leech infestation. If you do need the antibiotic, please follow this up with a good poultry or human probiotic. This should mitigate any stomach upset caused by the drug.
