I have 4 pullets who, for months, had been using the nest box religiously. Suddenly they stopped using it. I went out and had only one egg for the day. The next day, no eggs. I searched the yard and haven't found a nest yet. I locked them in the run to see if they're taking a hiatus or if I need to search the yard better. Yesterday I got two eggs. This morning, I found one near the nest box under the roost. The roost is high enough that the egg would break if someone had laid it from up there. Plus the nesting material inside the nest box was tossed about much more than usual. Everyone is acting healthy and it would be weird for all or most of them to suddenly become egg bound. They seemed very happy with the nest box at first. Do pullets take a hiatus? Has anyone had their flock suddenly not like a nest box they've been using? Our temps have been fluctuating wildly. In one week we'll have a day with a high in the 70's, go down to a high of 28, back up to a high of 68, back down to 12..all within one week. Would that do it?
