Well it looks like at least 3 out of 4 of my chickens are hens! I think the 4th one is also, but I don’t have proof of it yet. I retrieved the first egg a week ago, and after 7 days straight this is my bounty.
One day we had 3 eggs, that is how I know I have at least 3 layers.
If the chickens catch us checking the nests, so far, they are always happy and welcome us. Like they are so proud!
