We have 10 chicks. Some are delawares, black Australorps, partridge rock, Easter eggers and golden laced wyandottes. All are 8 weeks old. I have nesting boxes blocked off so they don't sleep in them and all are roosting at night on their own. 2 of our birds are cockerels, but we will only be keeping one. When should I open up the nesting boxes? I know they won't be laying for quite a while, but want them to have access before they start laying. How will I know when they are getting ready to lay? What do I put in nesting boxes for bedding? How do I encourage them to use the boxes? We're first time chicken owners, can u tell? Lol.
