I have 5 chickens: two 30-week-old Buff Orps; one 30-week-old Delaware; and two 27-week-old Barred Rocks. They seem happy and healthy. They have lots of space and eat a ton. They are big and have red wattles and have been squatting for what seems like ages. One of the Orps started laying maybe 3-4 weeks ago, but the others? NOTHING.
It has been a mild fall so I don't think it's the weather. I wondered if there wasn't enough nesting space because the one Orp is broody and sort-of hogs it, so I built 3 new nesting boxes and filled them with ceramic eggs. I'm sure they aren't laying them elsewhere.
What is going on? Does anyone have any theories as to why my girls are holding out?
