Hi Amber. How many Tiels do you have? Are they all 2 years old for sure? Are you positive you have at least one male bird? Tell me everything you give them to eat. How many eggs are there and when was the last one layed? Are the eggs in a nest box or where? Did your bird come from a pet store or a breeder or where? This extra information will help me give you my best advice for you and for the birds. Thanks, Patricia
