Black, swollen, featherless belly on my white zebra finch
(Red Deer, AB, Canada)
My white female zebra finch has a distended area under the vent & between the legs. It is black (charcoal shade, the skin is shiny & no feathers. The vent is not wet & she doesn't appear ill. She's able to defecate (white colored) without apparent trouble. The feces did stick to her & since I cleaned her that part seems better. Her diet is "Vita Plus" seeds mixture & "moulting" &/or "condition treat" as well. They ALWAYS have clean filtered water & daily (or every other day) they have warm bath water (using distilled water to avoid chlorinated stuff). She's in a cage with another zebra female & a canary, & I have 4 other finches (males) in a cage beside. This little girl (about 3yrs) was an awesome Mom & was a heavy egg layer - there aren't as many eggs now (no nest in cage). What may be the problem & what should I do?
