I am a new member, however have searched the site many times for valuable info and advice! I have a rainbow flock of 50 or so standard hens and a Partridge Rock Roo. I have set eggs in the incubator twice this year and hatched 10/12 fertile eggs and 16/18 fertile eggs in my Rcom20 incubator. Will set 18 more on March 9. The last 2 batches we sold/given to my cousin. Love chickens!
