just make everything accessible to her, we use bird water silo's for food and water because they can access it on their own even with an e collar on.
Use an OE pouch rather than a normal deep pouch so she can get in and out on her and keep things low in the cage rather than high like normal.
You don't want her being to active while she recovers.
Make sure the ejacket doesn't irritate the wound site and make things worse.
You'll also want to give her yogurt inbetween doses of trimeth sulfa, you want to get yogurt with live cultures, no artificial sweeteners and no non fat. Antibiotics destroy good bacterial along with the bad the yogurt helps to replace the good guteral bacteria.
Did they find a parasite in her? if yes is the cage mate also being treated with the parasidic med?
