Hey just a quick one - my duck has gone broody and is sitting on her eggs, I checked them today and they all have veins etc. We were going to boil them and put them back under her until we could get some other fertile eggs from a lady who supplies us with some of our birds (for her to sit on instead), because her brother is the father. I was away all weekend and by the time I got back and candled them they were all developing, is it cruel to boil them at this stage? (5 ish days) or would they be fine if they hatched? Because of the brother being the father. I don't know if they'd have horrible diseases or disfigurements.Would it be crueler to boil them at this stage or let them develop and die slowly of a genetic disease? argh!
