Duck mated chicken, chicken injured

[Cazook]

So she still hasn't been eating though she started drinking more and being more active once I put vitamins to her water. Was gonna end up tube watering her if she didn't start drinking, but seems she is now. I treated her for vent gleet bc it was actually disgusting. Her bum seems a lot better now but she is still only passing white water. I tempted her to eat 2-3 bites of yoghurt and chickcrumb mash but she just won't eat on her own. And this tube I have is too small guage to actually tube feed.

Encouraging a chicken to eat is becoming one of my most common banes in life now.
