I currently have six, 9 week old chickens in my flock. A few turned out to be roosters so I would like to add a few more to the flock. I purchased 4 month old pullets from a reputable farm in my area. My question is:
1. How do I go about feeding the 9 week olds and the 4 month old chickens? Do they need different food at this point?
2. Any tips on integrating the flock? Should they be added at night time? Should they be quarantined first?
Thank you all for any advice!
