Hi I am a newbie to all this. i got 10 eggs and a incubator off a farmer in wales on saturday. im hatching them with my 2 children and when there a few weeks old there going back to the farm were they will be looked after an we can visit them whenever we like (unless i get too attached and keep them lol) they have been in the incubator since sunday and iv candled them today and only 2 have hearts and veins. im a little worried because they have veiny rings round the heart is this ok?
