Hi all, I need some new chicken education please. I have 2 sexlinks (1 RIR and 1 Black star) They are both about 2 weeks short of their 5 month birthday. The smaller hen started laying last week. She laid a double yolker as the first and the next day a very small egg and nothing since. But she has gone into the coop and acted like she wanted to lay. Any help is appreciated. FYI: the larger hen has not yet started laying. Last bit of info...it has turned very hot here temperature wise this week. Any advice appreciated.
