My BO pullet started crowing I'd like to get a batch of chicks from him. I have two hens that are laying regularly, an EE and a Production Black. I also have 2 BR that lay once in a blue moon The cockerel is in a separate tractor with a CM. They are around 14-16 weeks, so I don't expect babies from her. I let them all out for a couple hours in the evening. When will the BO be able to make chicks? How much access does he need to the laying hens to get a fertile egg? How do I get the laying hens to sit on the eggs and hatch them? I'm so excited!
