About four weeks ago i moved the chickens to a new bigger run. from 8 hens i was getting 4-7 eggs a day which is normal. since i moved them a few things have happened. I made a new set of nesting boxes, we have added 4 new hens and 2 weeks ago a hawk attacked and killed a hen in the run. its also been a little colder this last week. we went from 4-7 eggs to 2 for the last 3 weeks. and yesterday there was none. the hens are going into and laying in the new nesting boxes and making divots in the hay. I'm trying to figure out if there just not laying because all of the stress i just caused them or if possibly i have a egg eater? when you have a egg eater are there any traces of a egg being eaten? if there not laying because of stress and the weather how long does that usually last? its been about a week.. this is only my second winter with chickens so I'm kinda new.. thanks
