The five hens I am buying are broody and want to sit eggs really badly, I will have eggs coming from a very nice guy on here (Thanks Ed!) that I am going to put under them to hatch (hopefully) are there any tricks to doing this? Once the chicks are hatched can I take them away and put them in a brooder then have the hen sit more eggs or will that exaust her (I understand most hens don't eat much while brooding...) I don't want to make the momma hen sad or worn out How many eggs can you put under each hen? (they are Marans) How long do eggs 'keep' for hatching, do they last a week or so? They should be stored at room temp right? Any hints/tips are much appreciated! thanks!
