My almost 5 year old Buff Orpington hen Funchick's belly is kind of swollen, it feels like a full water balloon and it's mainly in the front part of her belly. She isn't acting sick at all and is acting perfectly normal, eating, drinking and freetanging as all the others do. I just noticed how full it was today but I have felt that area maybe 2 weeks ago and it was a little but full of "liquid". Is she internal laying? Of had 2 internal layers so far and I don't want any more.
