Hello, new members here.

Welcome to BYC! Roosters are not a necessity unless you want the fertilized eggs. Also, in this case I would recommend only keeping one if you felt it was necessary. A general rule of thumb is 1 rooster per 8-10 hens. I would hold off on keeping one if you're not comfortable it is not worth the risk of injury to your little ones. Those spurs can do a lot of damage.

You have two options. Re-home or cull both roosters and wait until you want fertilized eggs to have one. Or just re-home one rooster and keep the best one for yourself. Most squabbling (pecking order) will sort itself out in a few weeks.

Also, if the hens are protected from predators and have adequate shelter in your tractor I'm sure they're fine. I would only worry if they have no cover from rough elements.

Congratulations on your new flock. I'm sure they'll make a great addition to your family

 

Hello and Welcome To BYC! X2, the only main reason you really need roosters is if you want fertilized eggs, they are pretty to look at (major reason I have them), they do add to the flock dynamics, and an early warning system for some predators. But they are dangerous with young children, and they can be darn rough on the hens even if you have good ratios, roos often pick favorite hens and those will get overmated.
If you do decide to keep them for fertilized eggs, they don't need to be in with the hens all the time, just for a week or so before you want to set eggs. With putting them in a coop at night, depends on how safe your tractor is, roosting bars themselves should be fine either place.

Is that your hoop coop in your avatar picture?

 

Welcome to BYC! Please make yourself at home and we are here to help.

You've received some great advice above.

 

I am all for NO roosters. Really good roosters are very hard to find.

Get yourself a couple silkie hens - silkies generally make great broodies. Lots of chicken folks keep a few just for that reason. You can buy fertile eggs of any breed you want when they are broody. Just swap out their (non fertile ) eggs for the fertile ones you bought. They will hatch and raise them like they were their own. Broody hens do it all and teach the chicks to be chickens - something an incubator will never do.

 

Welcome to BYC, Jennifer! Glad you decided to join our flock. I agree with drumstick diva when it comes to roosters. The recommended ratio of roosters to hens is 1 rooster for every 10 hens. Any more roosters than that can quickly lead to aggression, fights, feather plucking, and over-bred and battered hens. I replied to four posts yesterday, and one earlier today, where new members were having these kind of problems because they had too many roosters. When you really get down to it, as drumstick diva has told many new members, the only reason you really need a rooster is to fertilize eggs for hatching. 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, and over-bred and battered hens that frequently goes along with having roosters (especially too many of them). In answer to your question regarding your chicken tractor, if you're absolutely sure it is predator proof, then the roosting bars in it will be fine for them at night. Good luck with your flock.
