My neighbour has been offered some rhea eggs, I have offered to put them in my incubator (4 inch headroom) and understand they will take 30+ days. Anybody been there before me? They sound pretty cool birds, will they REALLY keep the foxes away? (Just had 'phone call, birds are no longer laying, so no hurry. Any information you could give would be helpful - between now and next Spring!! ) I've done the internet and got the basics, but any information (first hand) would be valuable!
