I have been reading and learning from BYC for over a year. Last spring I purchased by first set of chickens I ordered 6 and ended up with 2 roosters. I lost my 4 hens to the neighbor's dog and now only have the 2 roo's (Barred Rock and Ameraucana). I am in the process of ordering chicks for the spring. My plan is to get about 18 chicks (hopefully I will get all pullets) and get another coop to split up the roos and the pullets once they are old enough (9 pullets in each coop with 1 rooster). My question is what is the best way to introduce the roosters to the pullets once they are old enough? Is the 9 to 1 ratio (pullets to roo) adequate? Thanks in advance for the advice!
