My chicks are over 8 weeks old and have been introduced to the 2 hens I still have via a dividing pen. Things seem to be going well, and I had hoped to have them all together within the next few weeks, but the set up is untenable for an additional 10 weeks when they will transition to the same feed. HOW do others handle the different feed needs of different aged chickens in the same coop when they are free fed? I planned everything else, but did not remember this bit. If there is a lot of outdoor time for root for food, and afternoon fresh greens from the garden, is it still dangerous if the chickens eat from the wrong bin? (This will likely go in both directions, so the question is for both the hens and the chicks.). Thank you in advance.
