I am very happy to announce my first set of three silkies has hatched! They were in an r-com3, all automated. All are white I think, but one has no vault, one has a medium vault and one has a huge vault! I wonder if there is any reason for the size, like male or female? I called the local co-op and they recommend vaccinating for Marek's and then treating as needed for all other illnesses like pox, worms etc. These are my first chickens, and I am feeling a bit like a mom who has had triplets- have I bitten off more than I can chew?
