Hi, this is my first post and I am new to chickens. I acquired 3 hens for free that are in great health and are about 7 months old. This happend to coincide with my actual chick purchase of 5 chicks of different varieties. I was planning on keeping them separated initially and then while letting them share the yard, join them up later. I am sure with supervision and joining them all together at night that it'd work out. These chicks are about 5 weeks old. The problem is now I have been gifted 3 new chicks a few days old. Now I have 3 age groups and I feel like I in a pickle. How do I put them all together now?!? I have been affected by chicken math and now I need advice on how to manage this. Please help.
