Hello, I am new to the forum and also a new chicken mom. I rescued 12 chickens and a rooster from our neighbor who due to health problems, could no longer care for the birds. The rooster is a rhode island red, 6 white leghorns, 5 black leg horns, and 1 red star. The flock is about 2 years old. I have had to take care of the chickens before bringing them to my home for a short time while my husband built a coop and fenced in an area. I have been collecting about 5 eggs a day so far and that is what I collected before bringing the chickens home to. Not all the chickens are laying and I would like to know if there is a way to tell which chickens are not laying. Would their vent area appear different (smaller)? Also this is the second time in 2 weeks I got an odd shaped egg. The surface has groves. What would cause this? Appreciate all the help I can get. Thank you.
