happened 3 days ago. seemed like she was dead, then perked up. right eye bulged out of head put ice on it and eye got 90% better. right wing a bit week and both legs not very strong. right one is worse. now I noticed a "bubble" on her breast almost like air bubble just under skin. if I push on it I can see fluid. I've been feeding her sugar water and she has been drinking but just saw her spit it up and it was "mucusy". any advice on what to do for her? she looked like she would rally this morning, now she looks super weak. can hardly hold head up. doesn't move around or drink or eat on her own.
