I think you are making the right choice dropping the intentional cockerels from the order. By ordering 25 chicks, there is a fair chance you are going to have an "oops" cockerel in the order. You might get lucky though!After talking to my mom and reading more on here I’m thinking about changing my order. Here is the initial list.
5 Barred Rock Cockerels that we plan to keep the best 2 of and butcher the others. Then 2 pullets of all the following Americauna, Austra White, Barred Rock, Black Australorp, Brown Leghorn, Buff Orpington, Light Brahma, New Hampshire Red, Rhode Island Red, and Silver Laced Wyandotte
I got to wondering if the Rock’s could possibly be brother and sister and wondering if I should be ordering males and females at the same time from the same hatchery in case I ended up wanting to raise chicks out of them. After reading more on here I found where it was advised to not raise your roosters with your first and only batch of hens. Because they will outgrow the others and without guidance of older hens or roosters can become a nightmare. My mom also warned that she had some Buff hens and they became so broody that they would break the other hens eggs. So now I’m wondering if I should drop all the Barred Rock cockerels and Orpington pullets and replace them. My initial thinking around the Orpingtons was to possibly let them brood a variety of eggs if I ever wanted a self sustaining flock. I was only wanting a rooster to hopefully keep the hens from fighting and watch over them when let out to free range. I wasn’t planning on trying to raise chicks unless I somehow lost a bunch of chickens or something. But now I’m thinking about dropping the Buff Orpingtons and the male Rocks. I still need a minimum order size of 25. So I could get some extra Americana’s, Black or White Australorps, and Brown Leghorns and/or add some Black and/or Golden Sex Links and some White Leghorns. I could really use some guidance if I’m making a mistake. I’ve read the Black Australorps can be bullies and go after eggs of another breed. But my mom adored the ones she had. They are coming from a hatchery. So who knows what I will get I guess. That is some of my reasoning for getting such a variety.
As for dropping the Orps because of broodiness... any chicken can go broody. In my first batch of pullets, once they became hens, my RIR, BA and PBR all became broody. The BA went broody three times. The RIR twice. The PBR once but she wouldn't back down so I let her set 4 eggs and she hatched three.
In my second batch of pullets, four of the little stinkers went broody as pullets late last autumn. So you may very well get broodies no matter the breed although Orps and Silkies are rather notorious for it.
Where are you ordering your chicks from? Meyer Hatchery has a 3 chick minimum starting April 1. You get the best deal on shipping with a 15 chick minimum order. You may want to consider going there if possible and getting less birds to start. It will give you a better idea of what breeds appeal to you.
Then next year you can go shopping for a broody raised, multi generational rooster who is looking for a new home. They are available all the time. In all breeds or mixes of. That way you can get one that has learned some manners and has proven himself to be non-human aggressive.
