It’s normal. They probably also molted so their energy is going into growing new feathers. As the days grow longer, they will start laying again.This is our first winter together(my family and our flock) they’re 7months old.. I live in NY and it’s been freezinggg we haven’t had any eggs at all in over a week! Is that normal for them to go that long?! We have 3 pullets and 1hen.
