i read in a book that hens need to have at least 14 hours of light a day to lay eggs, is this true? it seems like the chickens have really slowed down as far as laying recently. it said that if your chickens are not getting enough light that you might need to put a light in the nesting box. i have never heard of this before, but it makes sense because the days are getting shorter but it is still fairly warm around here so there is no reason for the temperatures to effect their laying. has anyone ever heard this before? is it true?
