Wasn't sure where to put this, thought it might do the most good here in the chick forum. Yes, you can integrate your little fluff balls at a much younger age than you might think. Prior thinking was to wait until chicks were at least 8 weeks old or of a size almost equal to the older birds, so they would have a 'fighting' chance against the usual aggressive rejection of new birds by an established flock. It has come to pass that many folks are now finding that integrating much younger is easier for all involved. One thing has stayed the same tho, the new birds are kept in a 'see but no touch' adjacent pen for a few weeks prior to allowing physical contact. This allows everyone to get used to seeing and hearing each other without having to share physical space and feed/water. Here's a couple of key reasons why it works: Tiny chicks are less of threat to the older birds and their resources(space, food, water). Tiny chicks are a small target for pecking and fast as all get out - so harder to 'catch'. For easier composition/editing/linking I wrote and illustrated with pics how I integrate chicks in an 'article' found here: https://www.backyardchickens.com/a/integrating-new-birds-at-4-weeks-old Post any questions here in this thread as I don't get notifications of comments made on articles.
