Sorry for the long post, I am fairly new to the chicken world (having raised many other types of animals and livestock). I need some rooster help.
I am looking to keep between 20-40 laying hens. Currently I have 3 grown Rhode Island Reds, 7 IsaBrowns that are 9 weeks old, and a mix of 18 White Leghorns, Rhode Island Reds, and Easter Eggers that are 7 weeks old. That gives me 28 hens/pullets right now, but only 3 that are old enough to lay. Last week they all made it together in the new coop. By August I expect an eggalanch to start. I plan to raise another group of chicks starting late summer and will sell several of the hens in early spring.
After this group of Isa Browns, I will likely stay with straight breeds so my hens will have better longevity. I am raising hatchery grade stock and am not interested in show quality. I want practical birds that will be healthy, attractive to sell, robust, and of course lay eggs. Part of the project is to teach my kids to raise the birds and make some income from selling eggs and young laying hens. I realize there isn't any real money to be made with our operation, but with me footing most of the big bills, the kids will end up with some cash and learn some valuable skills. So far the coop building experience, fresh eggs, and raising the chicks has been great.
So I want to add a couple of roosters. At least for now, I don't plan to hatch out the eggs. With birds coming in and out of the flock periodically I was thinking the roosters may be helpful in keeping peace and order, especially when I try to add juveniles with the adult flock. Again, I am new to the chicken world, so I may be off base here. I don't want to feed the roosters if they aren't going to bring some value to my flock. I want roosters that will help my flock on a daily basis and not be overly aggressive.
So my first question is if adding a couple of roosters is a good idea, or should I just move on.
My second question is what breed I should pick if I add roosters. I was planning to raise a small group of chicks late this summer and could just get straight run and keep the roosters. My neighbor also has some sort of easter egger mixes hatching and has offered to give me a couple of roosters. In any even I plan to raise matching roosters from a set of chicks. That is just what I want to do. Breeds I am interested in for my hens are Rhode Island Reds, Easter Eggers (OK not a breed but I want blue eggs), Wyandottes, Australcorps, or Barred Rocks). I am trying to raise some different types of chickens to see what I like and because it adds interest comparing them. I don't want anything too exotic and the breeds above are easy to acquire and trade in my area. I will consider other suggestions though. So, since I am not primarily interested in genetics, please help me pick a breed for my roosters based on behaviour.
