does she seem to have alot of fluid in her abdomen? there is also something called ascites it's were fluid builds up in the abdomen, please use google custom search and look it up.
I agree with Robin's if she doesn't lay today that PM speckled hen and she could give some great advise since she has been through this many times.. I just hope she'll lay for you today or maybe already has.. and I am in Burnsville, sorry I didn't do this last night,
If she is egg bound you will need to let her soak as much as you can just make sure the water doesn't get too cool, then for the night put her in a dark room if you have tums you can crush one up into some warm water and try to get her to drink it..hopefully by morning she will have laid if...
