my brother brought me 3 killdeer eggs (was going to take them back but cant find the nest) Please help - How long does it take to incubate the eggs? -what temperature do they need to incubate at? - how do I incubate them? -do they hatch featherless or do they have the soft downy stuff like chicks/ducklings...? -what do they eat? -Is it worth even trying?
