Hello I am new here.....As of 3 days ago we have been hand rearing our first ever baby budgies. Unfortunately the Mother and Father got out of the cage, (accident) we are so sad about this...We have been hand feeding them for 3 days now with a syringe. The oldest one is 3 weeks old, what is the next step for this baby? in the feeding process? Any help would be great - thank you.Or would one of my other birds foster them?
