So I got my first egg today! It came from my Barred Rock. She is about 24 weeks old and has been eating layer pellet for about 4 weeks. When I got home there was a little egg on the coop floor and she was in the nesting box. She didn't get out of the nesting box for quite a while. I finally picked her up out of the box to make sure she was okay. She was much more mellow than normal. I then felt warm wet all down my side. She had filled my pocket with liquid and a rather large chunk of something that looked like cooked egg whites. I set her down to take off my coat and she ran to the water and drank for about 15 minutes. When I went to pick her up again a gusher of water came out of her mouth. I brought her inside and she continued to drink a ton of water. I took the water away and she cried. So I brought her out with her sisters and she started attacking them. Her crop does seem large but I'm guessing it is due to the mass amounts of water she has been drinking. Help! What is wrong with her? These are my first chickens and my very first egg so I don't know much but this seems really wrong! This is what the goo looked like when I emptied it out of my pocket.
