A friend moved recently and gave me 5 hens. 3 look like auracanas (they have ear tufts) and 2 are mixed breed chickens. Each day I am getting 1 brown egg and every other day I get 1 green egg. I'm wondering if these girls are near the end of their laying life or if there is something I can do to help them lay more? I'm new to this and have only had chickens for about 2 months. I also have 17 chickens raised from chicks, so none of those are laying yet. Thank you in advance to anyone who can offer advice.
