I cull and eat surplus cockerels and distance myself from them as soon as their sex becomes apparent and they are broody hen reared so I am not handling them like you would if they were brooder raised but my hens have a retirement plan if/when they stop laying.
From the OP's original post it seems to me that their chickens are not pets and they are viewing the situation dispassionately. In that case, I would say that having kept them through their non productive moult period and now approaching spring, it makes more sense to keep them for eggs whilst you raise new pullets and cull them when the stop laying to moult next autumn/fall..... assuming you are in the northern hemisphere and the birds are over 2 years old.
