I have 3 gold-laced wyandotte bantam hens that are one year old (hatched 4-2-09). They started laying last September and continued through the winter, though decreased. Well, spring is well on the way and they still haven't picked up their laying. Most days I get zero or one egg. Occationally two. Never three (since last fall). I figure this should be their prime laying age and time of year. I don't supplement their light, I fill their oyster shell dish regulary, they are eating/drinking/acting normally. They also get an hour or more every evening of free range time out in the yard. They are not molting or broody. Any ideas what the problem might be?
