I was given a link to a great article here on BYC on the topic of flock integration. I also have been given the same advice from other chicken owners about waiting til my younger chicks are about the same sized as the older chicks. My question is when does that actually happen? When they are all full grown? I do not have the space in my backyard to keep them apart for that long. I made a short video showing the size difference between the birds. If this is something you have done before and or know how it goes PLEASE take some time to watch and give me some feedback. I am a little nervous about putting them together.
