My ~1.5 year old BO has been laying a soft shelled egg every other day for the last week. I know this is normally a calcium problem but could it be anything else? Tonight, I got home from work at about 830pm, full dark here, and checked the nest box and she was in there. I soft shelled egg was there and it was broken and it looked like egg was dripping from her ( I forget what the egg laying pooper is called). She looked uncomfortable and has never lain an egg at this time of night before. Will added calcium help this or could it be a problem? Thanks.
