Today when I went out to check on my quail and found a female egg bound with a prolapsed vent. I helped her with the egg but I'm not sure when to do for the vent. is there anything I can do other than to push it back in?
Do you have photos?
@TwoCrows may be able to offer more tips for Quail, but I would treat it like a prolapse in chickens.
If there is still prolapsed tissue, keep it moist with an ointment - you can use an anti-inflammatory cream, honey, prep H, etc. If it's not too swollen, you can try pushing it back in, but if it won't stay, then keep the tissue moist with ointment.
Soaking in a warm epsom salts bath may help too, but my understanding is Quail stress easily, so use your judgement on how well she handles and if the bath might stress her badly. If she's lethargic, then it would be better to leave off the soaking.
Keep her hydrated. I would get some calcium into her. For a Quail, I would go with 1/4-1/2 Caltrate once day, extra calcium can help with retention.
Hopefully others will chime in soon.
