And that's the kicker. They'll start laying when they're good and ready. Chickens don't like change, and any little change can throw them off laying. Shorter hours of daylight doesn't help. If the roosters aren't constantly harassing, chasing and trying to breed the hens, they're not holding up the egg laying progress. If that is happening, though, it could slow them down. Your hens are stressed when that happens, and they don't lay well when stressed. You're the only one who can decide what to do. I will say, though, that two roosters for 8 hens can be a bit much. Just watch your hens for signs of stress.They all seem to get along fine. I do see a little segregation among the 2 breeds of hens, but I assumed that was normal or just a difference in the way they act such as the Araucanas perch, but the silkies huddle....things like that. We have grown attached to the roosters and really don't want to let them go, but we do want to see some eggs soon and right now we are not sure when that will be lol. Thanks again for everyone helping bring all sorts of knowledge to the table. This really helps guys!
