I had a look at the eggs and i know that you said not touch them but i wasn't sure of the colour so i took one out so i could have a look closer with the torch. Inside there seemed to be about 3/4 a darker substance with the rest being a bubble. I'm not too sure if the darker substance might just be yolk?? Also what will happen now that i have touched the egg?? Hope i haven't upset the mum too much!! Also if the eggs arn't viable would the hen be upset if they were removed?
