Welcome to BYC! Glad you decided to join our flock. Drumstick diva has given you the straight facts on roosters. The ratio of roosters to hens should be no more than 1 to 10. The only really good reason to have a rooster in your flock is if you want fertilized eggs for hatching. Roosters can be very hard on your hens physically; over-breeding them, injuring them with their beaks and spurs, and battering them. I currently have 25 hens, no roosters, and I get loads of eggs without feeding any non-egg laying mouths, without the aggression, fights, crowing in the middle of the night, injuries, and over-bred and battered hens that frequently goes along with having roosters (especially too many). As far as the claim that roosters protect the flock from predators, and lead hens back into the coop, there may be some value in that among the aggressive breeds like game chickens, but with the docile breeds I have raised over the past 50 years, I have never yet seen a rooster that was worth a dime at these things. I lost just as many hens to predators with or without roosters (and sometimes it was the rooster himself who ended up as the victim), and my hens went back into the coop just as well without a rooster as with a rooster. Please feel free to ask any other questions you may have. We are here to help in any way we can. Good luck with your flock.
