Hi, This is my first time dealing with sick chickens so I really appreciate any help. Last week we had warmer then typical weather. Two days ago I noticed my 1 year old laced wyandotte chicken shaking her head and sneezing every few minutes. She seemed to be eating fine. No discharge in eyes and no mucus. Now this morning I noticed my Jersey Giant and easter egger are starting to do the same thing. We haven't added any new chickens to the coop but we did just bring home two weeks ago some new chicks but they are still in the house. They have pine shavings in their coop, I haven't noticed any unusual poop yet. So far I just added electrolytes to the water. Any other suggestions would be greatly appreciated.
