Need help once again. Last evening I noticed one of my Guineas was not with the group of other Guineas. He or she seemed very sluggish and submissive, they were fighting it, and it would just hunker down to be left alone. I got my net and caught it to look it over good, there were no obvious signs of an type of trauma that was visible, but as I was holding it, this milky fluid started coming out of its mouth. Could someone tell me what this might be. Also, as I held this Guinea, it constantly kept pecking and grabbing me on the hand. Any advice as to what may be ailing this Guinea? Thanks for any info I could receive to take care of this issue.
