My chicks are 11 weeks old and have been roosting on the top bar since I put them in the coop at 7 weeks. I just opened the nest boxes to them today. I have an Easter egg in each box (does it matter that they are colored?). Should I part the curtains for a while so they see they are open? I know I have a while until they actually start laying, but want to make sure I'm doing things right. I have 5 girls, and 2 boxes open (using the third for storage).
