Sorry to hear about your loss..its always hard, isn't it?  Unfortunately my little white leghorn hen is not doing well at all.  I do not believe she is egg bound, but think it may have broken inside or something else happened.  She seems to have an infection I think.  Her back end is matted but dry and she stands more than sits. Very little poo and is mostly white stuff. And now for the last 2 days she has not touched any food or water and this morning she was laying down breathing hard.  If I take her out of her cage she'll walk a bit but goes right back in her cage and lays back down.  I have tried force feeding some water but it just seems to upset her.  If she is still alive tonight when I get home I will try some more aggressive treatments but I'm not holding my breath.
Really hoped for a better outcome.  I cured her of bumblefoot this past summer and really hate to see her end up with something else this serious.  She is my most people friendly hen...
Thanks for asking and if I get better news I will certainly let you know.
