Help with bantam egg with runny brownish yellow liquid

[janf1914]

Yesterday my 1yr. old bantam was acting like she didn't feel good. She seemed to be having trouble breathing, tail down, all fluffed up and wouldn't sit down. I isolated her and brought her inside. She continued to act as if she was having trouble breathing. Every once in a while she'd perk herself up, eat a little, drink some, and then she's go back to the closing eyes and trying to breathe. Finally at about 8:30 I came into the room and could here her wheezing. I thought surely she was on her last breath. Opened the cage and scooted her toward me. As I did an egg came out. Didn't look too good - kind of beige brownish (her eggs in the past have been more cream colored), it had a soft spot on the narrow end and lots of calcification on the more rounded end. This is the first egg she's laid this year. Today when I cracked the egg opened, it had no separated yolk and white. Just runny brownish yellow liquid. She seems fine now and I put her back in the coop with the others. Does anyone know what might have caused this? I'm hoping it's just a one time thing and the rest of her eggs will be fine and will come out easily but I'm not sure. Any help would be appreciated!
