friend had a broody girl so I gave her some of my fertilized eggs...3 cochin eggs and 3 cochin/orpington or cochin/brahma. she sat and on day 21 like clockwork one hatched. on day 23 friend pulled rest of eggs assuming none were viable. we opened them for learning since I am totally new to all of this and all three cochin eggs were duds...but the other two larger ones were fully formed chicks but very "wet" inside. I tapped them with a spoon to break and maybe 3 or 4 ccs of liquid ran out. Is this normal? Should she have left them longer?
