If you listen to all the people that quote and cut and paste from the ALBC breeding chart and all the other sites then your turkeys can't be laying in VT this time of year. But since they are that takes care of that. lol I'm betting you have had some warm weather and sunny days over the last few weeks or are you giving extra light?? Ours were also hatched last spring and just starting to lay but the weather here turned cold, gray, wet, snowy and they quit laying. First year hens lay very well and early, are your toms mating them and have you check the eggs for fertilty? If you are giving extra light then they are on the spring laying cycle and yes they will be on the down side of the laying cycle in the spring.
