4 month old zebra finch - smelly poop?

[finchlover24]

Snugglebutt is going to be 4 months old tomorrow. Within the past 2 days, I've noticed that some of her poop has a lot of urine that actually has a gross smell. She has a habit of pooping in the same cup most of the time (its like her personal toilet lol) so maybe that could be it? I don't think poop/urine should smell though... I have been giving her guardian angel so maybe that could be causing the smell and the yellow/greeny color? Here are some pictures. I've tried doing some research and it says bacteria/yeast but she has been acting absolutely fine. No change in her diet, behavior, or voice. Other than her poop, she's her usual self.

Her diet consists of regular Higgins vitaseed, lafebers vitamin granules, spray millet, and the occasional egg food when i have time to make it. she hasn't had any eggfood within the past 2 days so I don't think thats it. She does love her baths so maybe that could explain the excess urine but I don't think it explains the smell/color. Her vent is also not wet and I don't see her puffed or in the same spot unless she's sleeping.

Also, I figured I'd say it before its mentioned, I do not have an avian vet closeby. The only vet I went to for Cooper had no knowledge of finches at all.
Meds that I have on hand (not sure if she's too young for some of these):

Ronex
Tri Sulfa
Baycox
Baytril
Nystatin
Medistatin
Guardian Angel
NV Powder
AviGold
AviPow
AviCalm
Megabac-S
Avibios
KD Water Cleanser

PM'ing you

was this baby hand fed? part of a larger clutch?

[finchlover24]

cindy Yes, Snugglebutt was handfed and may have been part of a larger clutch but she's the only one that made it. Thankfully, her parents have FINALLY learned how to raise babies so I won't have to handfeed anymore Took this many tries but its about time.
