Hello everyone! I am a new member to the site I have a hen that is about 6 months old that seems pretty lethargic. I noticed two days ago she was acting a little strange while she had her feathers puffed and seeming to start trouble with the other hens by picking fights and making a low growl sound. Yesterday I found an unusually small egg in the coop (all the hens have been laying since mid August now) this egg was considerably smaller than all other eggs they have laid. I of course don't know which hen laid this tiny egg but just with this now lethargic hen I begin to wonder if it is hers. This morning while feeding them I noticed she was off a fair amount away from the others dozing off then walking with her eyes closed as if she was too tired to deal. So I walked right up to her (unusual for her not to walk away from me) picked her up without a slight struggle from her and noticed she felt a little thin in her breast bone area. I brought her into the house and whipped up some scrambled eggs which she ate slow and mostly with her eyes closed but she ate a good amount then drank water just fine. I waited for her to poo and she did it was a "normal" brownish color constancy seemed good. Her eyes are clear and her color looks great. As of now she is standing quietly in a cozy cage in the house watching cartoons with my son dozing off quite a bit and not making any sounds. Anybody know why the lethargic ness is going on?
