Thank you SO much, Finchly!
I guess we’d want her to lay any eggs already in progress - it wouldn’t seem healthy to me to “stop” them if they’re already on the way. I guessed we’d wait until she lays this brood. Does that make sense - or should we try to stop her now?
(We can reach our vet only by email, not by phone, so his advice is delayed...She hadnt had the egg yet.)
She is still sitting the nest, but tossed her egg food around sometime in the last hour.
