One of my black austrolorps has what I believe is sour crop, swelled, soft and squishy, I have fallowed the instruction on trying to get her regurgitate but have not been successful, I believe shes been this way for quite some time, not realy sure what I need to do. I think I massaged her to long because her face began turning red so I put her back in the pen, I'm sure thats what it is because she has a really bad smell.
