This little sweetie (Watermelon) has a chest that is sticking out this morning... my son caught her and held as i looked her over. I'm not seeing anything but a very squishy chest. So my question is if her crop is filled with yuck, would it be squishy or more solid feeling? Could there be an abcess in there? Should I separate her and only give warm water for a bit? It's my son's bird, so hoping it's not too late.
