I am sure you've probably already cleaned her up but just keep an eye on her, she will probably continue to pass all that was left, and that is good. Sometimes I have seen white messy looking stuff on my hens too and it's been okay. you can also trim her feathers some back there and that will help to keep the mess down, if she is perky and eating and drinking she is probably fine, You just need to slow down the egg laying process a bit to help her recoup. if anything changes be sure to get back on here quickly there will be someone to help. Also remember they poop and lay eggs out of the same vent but it comes from different directions. But normal poop is good. There is a Moderator on here named Speckled Hen who has delt with Hens being egg bound alot if you PMed her she would be able to help you more because she has been through it.
