Bare vent Area
I have four Budgies and noticed that one of them has a bare vent area. This is a male Budgie aprox..10-11 months of age. He's not over weight, eats a healthy diet of seed, pellets, veggies, couscous, soak mix..etc.. He gets fresh water and food daily. I also add a drop of Apple Cider vinegar to their water daily.
I do a vent check pretty much daily..this happened suddenly. There hasn't been any droppings stuck to the vent area, its not swollen, there aren't any lumps.
It is a mystery to me concerning what may be happening.
I hope you will be able to shed some light on this.
