I have one hen that walks in coop the last few days and starts yelling at what ever hen is in a box laying. I put a wireless cam in coop to see what happened in there. Today she did same then went into anouther box and sat until other one was done laying,that one left and this one went right over to that box and layed one next to the other. She sat ther for about half hour and I went out because I don't want any eggeating. I seen her eat a soft shell, and that is why I went out and got the eggs and brought them in. She is still sitiing there half hour later. She will not let any other ones in there to lay. I have 11 hens and 5 nest boxes. Been getting 3 or 4 eggs a day for about a week and a half now. They are about 4 and a half months old. What is going on??? I should have been getting 8 to 10 a day I thought.
