Kim,
It's something you will get better at, I have a Broody (Goldie Leghorn, the Belgian D'uccle Cross Frizzle) who was amazing and the 4 baby's are 8 weeks old, 2 X Silkies and 2 X Pekin's she is still mummy and only just starting to tell the bigger Silkie to go away. Not laying again yet. Ume my Silkie started being Broody and sat for 2 weeks and the 4 eegs were in my incubator. 3 x Cochin and 1 x Silkie. on the last incubator date I ran the eggs at night and put them under Ume. 20 minutes after (day 20) I had babies hatching. She was never a great mummy, and the 4 x babies turned 3 weeks and Ume started laying again like crazy I had 11 eggs, in just under 2 weeks. she wants to be part of the flock again back still tells the other not to mess with her babies.
Here is a Eggs Chart, I only Candle 3 times 7 days 14 days and 18 days before lock down.
Good Luck and enjoy this, it's amazing.
