Is the feed you offer a crumble or pelleted feed or a whole grain type feed?Oh thank you for telling me that. I'm reading everything the last couple of days to try and figure out how to help her. She just drank some water which is the first time today. Not eating but stood up to drink.
A vet's visit to teach you how to tube feed and water the bird and get some antibiotics is your best bet at keeping her alive.
If she hasn't been eating and drinking for days she's not going to last long.
Is putting a tube down her throat in to her crop an option for you?
