I am learning to use the FAMACHA eye chart to check for anemia. I have never seen the goats' eyelids as deep pink as the farthest to the left part of the chart. Has anyone on the board seen that? I dewormed the goats 16 days ago. All but one are now at level three. One was level one this morning, and I dewormed her with a different wormer this morning. How quickly should I expect the eyelids to pink up? Are there other factors that can affect the level of anemia / eye lid color?
