in mid to late September i let 3 of my game hens sit and incubate the eggs the nesting boxes that i had weren't cramped but they weren't huge either. i had two hens sitting on the same batch eggs. has anyone ever seen this? i split the eggs up and they separated. i had a few chicks hatch. i took a couple away and raised them by hand. the ones i left behind when they hatched the chicks i guess wanting to hangout and socialize with the others crawled into one box. which resulted in the hens all sitting in one box together. i left a few for the hens to raise naturally. that was late September now its January and i haven't seen one egg from any of the hens. how can i tell if they are either done laying for the year. i also don't know the age of them so what are some tell signs that they are to old.
