Hi, my budgie Harley is about 7 weeks old. He has been doing really well up until yesterday when I gave him a treat of a Trill brand Honey stick which has honey, seeds, currant and apple. He loved it but by the end of the day I noticed his poop was changing, and today it is watery. I took the honey stick out of his cage, and just left his normal budgie seed and filtered water.
He is still eating and flying around, and playing with his toys. Not puffed up or looking slow and sick.
I am assuming I introduced the honey stick to early for his age.
Now should I just leave it and wait to see how he is by the end of the day? now midday here....
Or is there something else I should do ?

Many Thanks
