Strange behavior in my BA

[J and M s eggs]

My BA is 8 mo old and started acting very strange today lethargic and a pale comb. I normally don't let my chickens out to free range . To day I did and when I do they go crazy . She scratched and pecked a little but not much she is acting very different form the others. Please help!

Look her over for lice or mites on her skin. Has she been wormed recently? Coccidiosis can be a problem if the henis new or you have added a new bird recently who may have brought in a new strain of cocci. Treatment would be 5 days of Corid or amprollium in the water. Symptoms are poor appetite, puffing up or huddling, diarrea--in some cases bloody, pale color, and ruffled neck feathers.
