I noticed my hen was acting different,she was off by herself and then when i gave her some food & water i noticed some liquid coming from her mouth. i seen this a few times happen with in the last three days. So for the last 3 days i kept her caged away from the rest of the chickens. i do let her out during the later part of the day to free range while I'm outside. She seems fine. She had a messy butt, so last night we washed her butt in warm water and cleaned her up. Her butt looked a little red probably from poop being there? she still is eating and drinking and she is alert and acts fine ,but I don't know why or what the liquid was coming from her mouth? Thanks, Julie
