I guess I'm one of those people who anticipate problems/questions years in advance. I think I just like to be prepared. I have 8 RIRs that are only 8 weeks old and of course I'm no way near getting my first egg. I got the chickens for egg laying. And as sweet as they are, I don't think I'll get so very attached to them. When their egg production drops a lot at age 3 or so, how do I cycle in new chicks to replace the ones I have so that I'm not without eggs for several months. I live in the middle of the city, with a small lot, and therefore I just don't have the space for a separate run new chicks. Could I replace half of the older hens at a time, so that I would still be getting some eggs? Or should I just bite the bullet and replace everyone at the same time? How do others with small flocks & limited space replace their older flock?
