Good morning everyone, I am a new chicken momma. Adopted 4 2 year old hens in March and have 4 two week old chicks. My question is this, everything I've read in the books say that it takes 26 hours to develop an egg. But so far haven't really seen 26 hours between eggs. Eggs get laid around the same time each day. Is this normal or are my ladies doing this because they are older?
