I have 2 Black Australorps 9 months old purchased a couple weeks ago they lay 1-2 eggs daily with occasional non laying. I have 3that are 7 months old, they are not laying yet. My question is should they be laying? They are free ranging chickens. Is there something to help the process along or no? Last issue is they do not lay eggs in nesting boxes they lay in the clean out tray???? Any help Greatly appreciated. I keep it clean and make sure they always have fresh food and water and some table scraps.
