Hello, I have a small mixed flock with a rooster. They are all pretty peaceful but grew up together. One of my hens is currently raising 4 chicks. I have a few questions: 1. When should I re-introduce mum and her chicks to the flock? They are currently in a pen a couple if metres away. The main flock checks on them while free ranging. 2. I'd like to buy a couple of new pullets and a few young ducks. Should I introduce them at the same time as mum and chicks to the old flock? 3. Or introduce the new comers to mama and chicks first then later to the flock? 4. or wait until mum and chicks are back in the main pen and use the spare pen for the new comers? 5. If using option 4, can I put new chickens and ducks all in together before introducing them to the flock? Thanks!!
