For Gouldians, some breeders do not chance this and wait 8 weeks since gould chicks can take longer to figure out how to shell seed. Providing millet spray, soak seed, and sprouted seed will encourage them to try eating on their own. Since finches do not do much perch eating most species of twigs are fine. I have used the following hardwood species - maple, oak, ash, beech, hickory. Since these species are plentiful near me, this is what I will keep using.
Diameters probably vary from pencil thick to twice that.
Back to top 6 - Society finches are monomorphic. This means the two sexes look alike and there is no reliable means to tell them apart without studying their behavior. Their throats can be seen quivering. They stand upright and send out a soft unimpressive song. Hens only chirp.
