My hen has watery diarrhea

[debrobbins]

My 1 year old Buff Orpington has watery, clearish diarrhea. She has stopped eating and is only drinking alittle. I've cleaned her up and have tried to offer some treats but she's not eating anything. I've started giving her some sulmet in the water yesterday but she hasn't responded. Is there a way to administer this in a more concentrated way? She's been this way for a few days now. Any ideas and any help would be greatly appreciated.
