How large do CL knots get before they bust? I have only read that they get about golfball size before the skin busts open. I have a 2yr. old and noticed a knot on the side of her face towards the back of jawline...her ear covers it and I didn't see it until today. It looks like the size of about half a tennis ball, still has hair on it. She wouldn't let me get close enough to inspect it...I will have to have someone to help me hold her and look. I did put her in a separate pen from the rest of the herd until I figure this out. Any suggestions?? I included a picture about 3 or 4 posts down. UPDATE!!!!--We went out to do the formalin injection and the knot was already draining. It is not thick and pasty like CL has been described but more of a white liquid pus. Still has hair on the knot.
