Hi I am new to the site and keeping chickens - we got our first hens 1st Dec 2009 - 2 Rhode Island Reds, course they are so addictive we have added and added and now have 10 hens and one cockrel (he was a surprise as bought as a hen. My hens/cockrel free range most of the day with my neighbours hens and cockrel and are all the best of friends. I purchased the King Suro 20 incubator and set 24 eggs yesterday (my first attempt!) so I am with you. Very nerve racking. I was not as organised as you seem to be so I dont really know whos eggs are whos apart from my blue egg layer and my dark sussex who's eggs are very pale compared to the others. I have set 4 of my neighbours eggs for her too. The instructions on the incubator were not well written and didnt really tell you how to set the eggs so I have followed the photo on the box with big end up - hope that is correct. As I have never done this before will I know who fertilised the egg my cockrel or the neighbours mine is a light sussex hers is a bantum - will the chicks be a cross breed or do they take the breed of the cockrel or hen - sorry if these are silly questions! Will keep you posted on progress. Also what do you do about vaccinations - I have read many forums on this but doesnt seem to be any hard and fast rules if you want to sell the hens later do they have to be vaccinated?
