Hello there and
to the forums!
I agree with Aluz, my own little budgie often has warm feet. If they have been particularly active, like after flying or playing with their toys, the blood flow to the feet is increased and it makes them warmer. As mentioned, she also could be hot. Even though it isn't summer, your heat could be higher than normal or the room could be absorbing lots of sunlight from a nearby window.
At any rate, it's always good to take our little birdies to an Avian vet for a check up and establishing a good relationship with the vet will certainly help to ease any worries!
Keep us updated on how the vet visit goes!
In the meantime, be sure to read all the stickies (or important threads that are "stuck" to the top of each subforum for easy reference) to ensure you're up to date on the best practices for keeping budgies
Hope to see you around, and if you have any questions after reading through anything, please ask!
Oh, and we love
pictures around here, so if you have any to share, we'd love to meet your little budgie Spritz!
I'm glad you've joined us!
