I have 6 hens who are all around 9-10 months old - typically since they started laying we were sure of 4-5 eggs a day and sometimes 6. Recently, for about 2 or 3 weeks, we've been down to 1, 2 or 3 eggs a day. I haven't changed their food, they get some scraps a few times a week and they are behaving normally otherwise. We did just find one egg underneath the hen house but just the one. We did introduce 3 new buffs about 6 weeks ago (stupid, I know, having subsequently read the advice), one of the buffs died suddenly 3 weeks ago and I've been monitoring them all since and all seem healthy. Any ideas? Thanks in advance!
