So I checked on my chicken and she was fine in the morning. Later on in the day I see that she has what looks like clear slime in her mouth. She eats and drinks normal. Her crop feels normal. So I let her be. The next day (today) I check on her again and she still has the slime in her mouth but doesn't eat or drink. I see that she wants to , but her body won't let her. Any help ? How can I help her ?
