I have a Silkie that has started laying her first eggs here in eastern VA. If the eggs get a bit of poo on them, should I scrape it off with maybe a fingernail or leave it there if she sits on them? If she starts brooding, will they hatch this time of year outside? What about the chicks, won't they get too cold? She is laying in my small coop that several other chickens go in, should I try to get her to start using a smaller, private box? OK, what about chickens that ar on antibiotics like Tylan. Will their eggs hatch??? Thanks!!
