Hi! My Tiels are about 1 yr old. They recently started laying eggs. They have a nice nesting box. They have no nesting material as everything I have tried, they have thrown out. The female will lay an egg, roll it around in the box and then after 12-24 hours she throws it out of the box into the cage. Am I doing something wrong? I am at my wits end!! Are they to young? Any help would be greatly appreciated!! Thanks.
