I am new at this 1 of my 20 week old production reds started laying last weekend I have gotten 5 eggs, but 4 of them have been broken. I check multiple times a day for eggs and to visit with my chickens. All of the eggs have been in the run and not in the nest box, so my question is how do I get her to lay in the nest box and not the run? I feed grower feed with oyster shells on the side right now because I have 11 week olds upto 20 week olds ( a total of 5 hens). They are not freeranged, but are let out for a little while to play with us.
