I have a few hens that are approaching laying age. They are around 20/21 weeks and I have noticed reddening of combs and larger wattles. No vocalizations yet, no squatting. My question is this...if a hen comes of laying age in the fall will they wait until the following spring to lay their first egg? I’ve heard that some stop laying in the colder months when there’s less daylight. Will this mess up the ones so close to laying?
