Last year I had a turkey hen that continued to lay for a week after she went broody.... All other turkeys had been broody for week or more and not adding to any clutchThis real interesting. Pullet designated Maple is broody and still in lay! She does spend more time off nest and is eating most of the feed being applied. She is eating more feed now than when she was simply in lay, totally in the face of what I have always "known". Late deposited eggs will not hatch in time to leave nest with balance of brood. I have seen many larger clutches with embryos that fail to hatch because late in developing. That may be a function of some laying into broody cycle. Conditions are artificial where the pullets are confined. I wander if pullet doing this might be the ones most likely to sleep eggs into nest of others, a form of cuckoldery.
