Visit to the avian vet, again

UPDATE Tommy and Ollie! First of all. Tommy is fully OKAY! This blood test (phosphates) were very normal, so it was good to retest the blood. That his poop is not as normal is probably because the cloaca muscle is a bit more slack. That also can give some bubbles in his poop. But this is nothing to worry about. Now.... Ollie! I took him to dr. Peter too, because his poop looked so weird last weekend. To make a long story short... Ollie has a yeast infection in his intestine. I am so glad that I also took him to the vet. He now has meds (Nystatine) and I give it in his chop - rice and veggies - and tonight he still ate it very good.
I THINK that Ollie sometimes eats from his poop. I really dunno why he is doing that, but that is the only thing I can think about, that he now has this infection.....Tommy's beaky is also trimmed again. It already was almost 3 months ago.
