@Eddie12109, I was wondering if you’ve been able to tube feed her yet. Another possibility, other than soaked, regular chicken feed would be raw egg yolk, which has the nutrients a chicken needs (but not forever or in place of their feed.) Also, make sure anything you feed her is a little warmer than room temp. In her fragile state she needs to stay warm.
I promise this is my last comment about euthanizing her. If you, the owner, the one who loves the sweet girl, cannot be there to tube feed her, I would not leave her in the hands of family members who have no connection to the hen. Generally speaking, those who have no vested interest in something tend not to care enough about it to do it correctly, if at all. Not to mention if they’ve never tube fed before.
I do wish you the best in taking care of her, I really do.
