I am a newbie with silkies at laying age although none have laid yet (26-28 wks). I have one hen who acted bizarre last week and now is very quiet, not eating or drinking much but does eat and drink a little. She is very quiet now and more docile than usual. I visually inspect her daily and do not see anything abnormal with her vent, nostrils, eyes, beak or ears. I gently palpate her abdomen and chest when I hold her and nothing unusual. She does not pant, seem distressed or anything, just tired. She mostly sits and is all fluffed up and stays near the water and food. She seems to want to eat sand more than anything but will eat the scratch I throw down. I do not see any evidence of mites or lice and the other hens are all acting normally. It seems as though she has lost weight in the last week and her stools are definitely smaller -- but she is eating less. They also seem pale. Any ideas? I was planning on giving vitamins and dewormer -- they have never been wormed. Thoughts? Thanks!
