Actually they're only 2 weeks apart, but boy what a size difference!!! I'm wondering if anyone has had experience integrating them together. I've attached a photo with what I've already done. On the left are the 2 week old chicks and on the right are the 2 day old chicks. In the middle is a makeshift screen I made so the little ones could have their own space for a bit. Some of these are going to other homes today, but the rest are staying. Hence my question. Thanks for your input!
