My bantam brahma is sick, i think she might be too far gone. It started yesterday, when i noticed her crop looked big and all she did was drink water.I picked her up and she threw up a little. I gave scratch, wouldnt eat it. Just standing by the water drinking. Today i have been watching off and on, still no eating, only drinking. she also isnt doing too much. Tonight i went to close up for the night and she is breathing through her mouth, making small noises. Any thoughts?
