I have new birds that we rescued some people have said that they are belifielders, they started laying eggs at about 4 m old. They laid about 8 eggs each but they thought that they were sitting on their eggs but they were sitting on plastic eggs. It has been about 21 days and they are now getting off the nest more, but I have one that will attack the other one but not while they are on the nest. What can I do I really don't want to give one away or anything. Need some advice
