Hi I have a white leg horn hen that ,in the last few days, isn't doing so well. She was laying eggs everyday until the last few days or week. She would go into a nest and just sit there, no egg. Now yesterday I noticed that she wasn't eating,or drinking. She just stands beside the food and water feeders and does nothing but close her eyes. I don't know her age, but know she is getting up there. Today I checked on her and her comb is slowly turning blue...or purplish. I touched it and it's cold. Her comb is usually very red. She doesn't seem to want to move anywhere. Could she be egg-bound? Is there anything I can do for her? Thanks ahead of time for any advice or ideas.
