Since I am fairly new at raising chickens I have a question about egg laying. According to a "chicken book" the hens need about 12 hours of daylight to lay eggs. My 5 hens are now 6 1/2 months old and have been laying eggs for 2 1/2 months. The daylight hours at this time are about 12 1/2 hours. My question is will a hen quit laying all at once or will it taper off? Thanks for any help.
