Good afternoon, sadly the two Mosaic red browns died at two weeks through lack of feeding although the parents were trying. The chicks would call for food but not open their mouths. For me this is down to leaving the nest too early and I will not put the nest down to cage floor anymore at 13 days like many people do as I am not in a rush for them to build a second nest. I have three Yorkshire eggs and four Mosaic yellow agate topaz eggs all fertile and due to hatch over the next few days. My Fife chicks are now a week old and all three have been rung.
