Overproduction!!

I have a flock of chickens 40+ of different ages some 3yr 2yr etc

My husband feeds them the highest protein feed and they produce like crazy. We lost a big buyer (out for maternity leave) who hatched chicks. I told him I think we should change feed to slow down I don’t want the eggs to go bad. He said they should be fine but I don’t think we would sell as good as we did before. I was thinking of switching them to cracked corn or something. Any recommendations?? TY!!
