My 7mo. americana hen has never layed an egg. The rest of the flock is laying. I found her under the coop strugling. I think she has a binded egg. Her vent is protruding and she is contracting. I have given her a warm bath, liquid vitamin supplement. I have isolated her from the rest in hopes she can relax. I'm so worried and dont want her to sufer. Am I missing doing something to help her? Does anyone have any suggestions? We love our chickens!!!
