diarhoea

(I don't know where to put this, so mods can put it wherever appropriate if this isn't) (FYI: My timezone is GMT+3) "Again" meaning I took my cockatiel to a vet this Oct 2nd because of stool/poop suspicions (notably seeds in stool, bubbles in stool, the vet noticed diarrhea too). "Saturday"...

Hi I have a female cockatiel, about 3 years old. Shes in season at the minute. Past two days her big poos have been very runny. Her little ones arent as runny but still not quite right. Hasnt had a change in diet and is not acting differently. Is it something to worry about?
