I have been reading many threads on the site and love what I've learned until I came to the Emergencies/diseases/injuries and cures section. Now I am terrified for my fine feathered friends I want to know what these diseases look like so I can be prepared if my hens get these...my problem is impact crop sounds like you have an insect infestation in the garden (not really a chicken issue). Could some of you all post pictures and or discribe what they are? What is Impact crop??? What is Lice, mites, etc??? What else should I be aware of??? How common are theses??? Can someone just reassure me that my hens will live long and be great family members? HELP!
