Are you checking bright in the morning before they get food? Birds will get a huge crop (or just a big crop if they're normal and don't pig out as bad as mine )) because they grind food in the crop
It being like this for month now and she moving very sick
What food does she have access to? What are her living conditions / what surfaces does she live on / bedding etc? What symptoms of sickness is she showing? Can you get better pictures of her crop and ones of her poop?
