I ordered 15 chicks from McMurray, 3 each of Buff Orpington, Black Star, Red Star, Black Australorp and Araucanas/Ameraucanas. My husband wanted a Black Jersey Giant roo so we got one of those as well as the free exotic chick that McMurray throws in. These guys are so much fun! So happy that I decided to get into this! Unfortunately in the first few days we lost 3, one was smooshed while they were sleeping and a friend accidentally let the dog into the basement and two were picked up roughly. I know that one was a Buff and one was a Red Star that didn't make it, the other was black but I am still not sure which it was, we are hoping not the rooster. Cut to six weeks later and I am guessing it was one of the Australorps as there are two of the 6 black that have very shiny feathers with an emerald (purple) tint to them. Anyway assuming that the Jersey Giant rooster made it and the free chick is also a rooster (he has an enormous comb already compared to all the others, which I know isn't fool proof) that leaves me with 2 roos and 12 hens, how many hens do I need to keep them both, I am quite fond of my mystery man. We have an 8x8 coop, with an attached 16x16 run and they will be able to free range on about 9 acres. I have heard on the low end 5-6 per, which I have but up to 10 per on the high end so I am thinking of adding another 5 pullets at the end of Sept when they would be the same age as my current flock to provide more hens per rooster once they mature. But not sure if this is necessary/advisable given the stress for them of adding new birds? Also don't want to make quarters too cramped. Thanks!
