I have a broody hen raising 6 chicks that she hatched. They are 3 1/2 weeks old now and I plan to move them to the coop with my other two hens when they are 4 weeks old. I know there will be some concerns introducing them to the flock but I am not overly concerned and have somewhat of a plan to handle it. However, I am concerned about feeding the chicks with the hens. The hens need the layer feed which could cause problems for the chicks. I do have oyster shell available for the hens but like the assurance of giving them the layer feed. I don't know how to ensure the chicks don't eat the layer feed and that the hens don't overly eat the chick starter/grower and miss the calcium they need. If any of you guys have experienced this or have any ideas please share. The coup is 4x4 and I don't usually put food in there. The run is 8x16 and I could section a portion off for them but I don't have separate housing for them.
