Good evening everyone. This is my first time raising chickens I live in south Carolina. I have a hen that has been in the coop for three days . She will come out to eat and drink bit goes right back in. I am scared to move her or make her come out because something can be really wrong and I don't want to hurt her. What could be wrong? I have been reading some of the forum where it could be her vent clogged and put her in warm water and Epson salt. Bu I want to see what else it could be. I have 4 buff orp and only one stays in the coop. Please give me some advice or suggestions.
