I have a small backyard bunch: a Rhode Island, Plymouth Rock, Blue laced red Wyandotte mix, (all between 30 weeks and 32 weeks) a Polish (24 weeks), and a Red Laced Blue Wyandotte (22 weeks). I got 2 eggs in a week or two and thought they were just starting and that it would pick up. Then I introduced the younger girls to the older ones, which I anticipated would stop egg production until they got used to each other. Then I got 3 more eggs throughout a few weeks. It has been maybe 2-3 weeks since the last egg was laid. I'm so confused. I live in Northern California so it's been pretty warm, but not over 95 lately, and then only a few days in the high 90's. I am feeding the older girls an organic layer feed (Scratch and Peck), and the younger girls a grower feed still. I have fed them oyster shells, put apple cider vinegar in the water, etc. They are in a run most of the day and free range for about an hour in the evenings before bed. They have fresh water and I change it maybe every 1-2 weeks. The younger and older girls still seem a bit separated, but they get along generally. The Polish is the only real outsider, which is a different post. (She won't go to roost/coop with the other chickens at night). Any help is appreciated, these are my first bunch of girls and I'm getting rather frustrated!
