Yes.

If you have a dozen roosters in a pen, you will still have a dozen a month later. If you have two roosters in a pen, you will have one a month later. (?a day later?) At least, that's my experience. Not sure the ratio of how many hens one can service, can you make two pens??

I have one rooster and 23 hens and have about 80% hatch rate. Have also run two roosters on the same amount of hens but they were from the same hatch and just got used to each other and lived in peace. Did find one a home. If you have more than one rooster your rate of fertility may go down as one will spend a lot of his time interfering with the other in the mating. Kinda of like a bunch of young fellas all interested in the same young lady.

Thanks Simpleme for the info. 80% is good enough for me. I'll stick to the one rooster for now.
