Yes morehens disease is a very serious condition! Last year I started out with 12 white leghorn hens and roo. I now have 25 leghorn hens, 1 RIR, 2 barred rock, 3 mixes and a Delaware roo. That's not counting the chicks 18 RIR,3 Delaware, 1 Black Orp, 6 Jersey Giant. I also have 25 more chicks on order :/ Edited to add I forgot about the 7 eggs in the incubator oops.
