I have one Barred Rock, 2 Black Australorps, 3 Buff Orpingtons, and 2 Easter Eggers hatched October 26th 2016 and some started laying the Sunday before Easter (22 weeks) and others took a little bit longer. Now we get between 6 and 8 eggs a day. Usually 7. Last week we got 4, 6, and 6, not sure what happened to slow production or if they just took a break or what, but then yesterday we got 7. Anyways, usually it's one of the Easter Eggers and one of the brown egg layers who take a break. The others have mostly been laying an egg a day since they started. I think one of the original brown layers took a break once a month or two ago and I've gotten a few broken ones when the second EE finally started (one EE was the first to start laying along with a brown egg layer) but now they're all back to laying normally. And they never go on strike or anything. If they do stop for one day, they are right back to laying the next. These are birds that are supposed to lay 5 eggs a day, the Orpington is 3-5 I think, yet here they all are laying every day mostly. I sometimes keep track of how many we get a day but it hasnt been consistent. I think I'll start keeping track again and see how many they lay a week. Maybe try to identify the eggs too. But yeah, sorry, got to rambling, but sometimes birds lay better than expected
