So, I have no removed 2 roos of the original 9 birds. I took out Randy & Goldy.
Randy is the brown. He came out because he wouldn't leave the hens alone enough.
Goldy (the Manchurian) came out because the little English White roo decided he had to go. I intervened in time & got there when only a few feathers were gone & a small injury on the scalp - nothing that won't heal easily. However, Goldy is pretty upset to be by himself in a small pen. I'll give him nicer quarters tomorrow, but I wanted to watch his injury for a day to make sure it isn't worse than I thought. (So far, it seems fine.)
That leaves Spot (the EW roo) and six others...at least five of which are hens. The EW isn't tearing anyone else up yet...
I decided that the EW stayed in with the girls instead of the Manchurian because of the color genetics. If I am understanding the basics of this right, the white is recessive and the gold is dominant...so by keeping the white in with the girls, I'll get a much better assortment of colors. That, of course, is assuming I decide to hatch more. It'll be several months, at least, before I do. (I have enough for 6-7 eggs a day now, plus my button eggs. That is enough for me to have an omelet daily, or my son and I to each have an omelet every other day.) I won't hatch more until my older girls quit laying or reduce too much.
