That should be fine.So since they likely won't be laying much over the winter would you say just sticking with the Starter feed through the spring and then switching to Layer feed would be realistic?
And what is "laying age"? As I mentioned ours are 17wks currently.
And laying age will vary wildly by bird. Earliest would be around 16 weeks, which would be more likely with production types (hybrids, leghorns) but some birds can take as long as 8 or 9 months to start (more likely with low production/decorative types). With onset of winter, that will likely push back onset of laying by at least a few weeks, but it can sometimes push it all the way closer to spring, when day lengths start lengthening again.
