I recently acqwuired two java finches & put them in a large flight cage with another singler java. The new ones kept attacking the one I had - so I put the single in it'd own cage. The two new ones in a large flight cage make horrible 'bleating' sounds constantly - the noise is very annoying. These two new ones have lived together for about a year befgore I got them from "Petsmart". They have good supply of water, excellent food and all other things for them to interact with - help - I am ready to return them to the store.
