I'm a newbie! I have 5 Black Copper Marans hens that are almost 20 weeks old. None have laid their first egg and have all been very healthy in both coop and free to roam the yard. Yesterday, my one hen, Dottie, started acting differently than the others. These are her symptoms: keeping one eye closed more than open; resting more than the others; eating and drinking just a tiny bit; losing quite a bit of fluff feathers wherever she laid, but not today; diarrhea-like stool. I have done the following: inserted lubricated gloved finger in top hole in her bum to feel for broken eggshell-nothing; soaked her bottom in warm water; tried to cool her down keeping her inside garage for a little while. Today, I'm keeping her in the coop as I'm afraid my beagle will sense her being "down" and go after her. Can anyone help me, please? I'm really very concerned about her. Thank you.
