So, my chicks are getting big, they are around 6 weeks old, I think. Its time to consider adding them to the flock. I am thinking of building a small temperary wire cage and putting that cage into the hens living area. This way the girls will be exposed to each other while not putting the chicks at risk. I feed my hens laying pellets, how old do the chicks need to be before they get laying pellets??? And scratch?
