For the record......these chicks have been living on Purina feed, purchased from a family run feed store just down the road.
The chick starter was 18% protein.
The grower (flock raiser) they have been on, which I now suspect was the wrong stuff, was 20% protein and low calcium (around 1%)
The layer stuff they are now being transitioned to is 16%. protein and about 4% calcium.
As per Purina, for layers, they would have you feed the chick starter exclusively (never use the meat bird grower stuff) until about 18 weeks, at which time you transition them over to the layer feed. I've seen other feed suppliers suggest you start transitioning them over to layer feed at 16 weeks.
Whatever the case, these 14 birds were raised together until age 15 weeks, at which time 4 of them were moved elsewhere and put on layer feed (not Purina). Those 4 are now laying 3 eggs per day and have been for the past week or so. The remaining 10 were left on the grower feed until yesterday when I started transitioning them over to the layer feed. Of those, we are getting 1 egg per day and have only gotten 3 eggs total from them. Not bothering me any.....they start when they start......but found it an interesting thing to see this play out.
Stranger than science. (poultry science
