Lack of air circulation. Pressure on the lungs.What does a purple comb indicate? I’ll feel her abdomen when I next get out to see her. I felt i before but there was no obvious large mass. I think I may give her a day or two with no chemicals (spinosad or safeguard) in her system to see if she can improve some, if not I’ll have to cull because I just don’t want her to be in pain anymore
