Hi I have a silky I have had for a week and for the last 2 days she's has been quiet and sleepy not even leaving the hen house in the morning. I have isolated get to our laundry, filled her water with electrolytes and given her some boiled egg. Isn't walking around just standing and hanging her head sleepily. Will drink if I put it under her beak but otherwise looks so miserable. Any suggestions/help?
How old is she? Has she been accepted into the flock or could she have been kept from food or water? I would be tempted to treat her for possible coccidiosis with Corid (amprollium) in her water. It is a cattle medicine at feed stores. Dosage is 2 tsp of the liquid, or 1.5 tsp of the powder, per gallon of water for 5 days. Then treat her with some probiotics and vitamin s in her water for a few extra days.Then I would worm your flock with Valbazen a few days later.
Lice shouldn't kill them, but mites certainly can. Sorry for your loss. Silkies can be a bit on the delicate side. I still would recommend Corid for possible coccidiosis, and it won't do harm. Let me know if you need the dosage. Here are two articles on mites and cocci to read:
