From these two threads you said you took a chick from it's gouldian parents to give it to the society hens to test the society's. I didn't see anything about moving a tossed hatching egg. You are testing those society's again with another chick? Seems to me having the birds vet tested would be a LOT more accurate.

"I did not mean to give the society hens a blue chick to test them with. Oh well, what's done is done. Now the wait to see if the society hens can keep it alive to weaning."
"I would normally wait for a tossling. However because the parents were being good this year, that wasn't happening. And I needed to find out if the hens are clean or not, as the society hens have been in extended quarantine for a year."

"Well it just fledged."
"This little guy just is not begging like his siblings downstairs.
The 2 siblings are BEGGING as soon as the parents go into the nest.
This guys hardly begs. I was watching the societies. They go up to him and make the head movement like they are regurgitating and going to feed the chick. But the chick just sits there w/o begging."
"Right now, it is the CHICK that is not eating, rather than the societies not feeding it. I have been watching the societies go up to feed it many times with their beak up against its beak, and the chick would keep its beak closed. It accepts the food from the societies only a portion of the time that they try to feed it."
"It is possible that the societies are NOT "clean," and are carriers of C&C. And thus the chick has C&C, which could be why it is not eating as much. In which case I have to dispose of these societies or give them away, but NOT to a bird shop or anyone owning gouldians."
