Basically any show bantam generally lays eggs feb or march thru july or aug at most.
I raised a lot of cochin bantams and never depended on them for eggs other than for showing and exhibiting the offspring.
you should get enough eggs to incubate offspring at any rate
I kept a 100 watt lite bulb on them, in the chicken shed, all winter so they ate and drank to keep their bodies in fit shape. also kept heated watereers on in the shed
I fed only 16% laying crumbles NO corn
Some times soaked (in milk whole) oats so their bodies didn't get fat on them and ruin the possibility of getting eggs to incubate. Some birds tend to gain fat in their bodies and cause slow laying.
I mated one to two females per one rooster in cage sttings
I also pulled (slowly one feather at a time) in a 3 inch circle the vent feathers off the males and females
as cochins tend to have too many feathers and the males sperm gets deposited on the vent feathers instead of inside the hen.
