i have 4 easter eggers that are 14 weeks old,and i just got 2 black astrolops that are a year old .I have had them for 7 days and they have not layyed a egg yet..I have caught one of them nesting in the box a couple times but never produced a egg yet. I am new to raising chickens so i was looking for any info to help me understand them to know why they havnt laid yet?
