I have a 3 year old Speckled Sussex hen who has a swollen bulge under her vent. I noticed that she was laying in the woods about three weeks ago but she was still eating and roosting at night. When I looked closer, she had the beginning stages of a poopy bottom but I left it as is as she was...
I have a 1.5 year old speckled sussex that stopped laying about 2.5 weeks ago. She acts completely normal, very active, very chatty, eats very well, but no eggs.
I feel a firmish bulge below the vent that is larger than the other hens. You can't really see anything amiss as she has feathers...
