I also recently inherited some hens from a family friend. 3 of the girls were laying within a day or two - 1 joined in after a week, and 2 have only just started laying after 2 weeks. The 3 late starters all came via an interim home where they didn't lay at all (not happy with the geese already resident there) - so I think it just took them a while to get over the stress, settle back into the group and get laying.
Thanks! I think they are starting to feel more at home, they are even getting used to our two cats, and are bossing our original three around a bit less! I keep checking the coop for eggs, our other three are too young to lay, so these will be our first eggs. I will try to be patient and not keep mentioning sunday dinner
We got two EEs from a neighbor that had been laying and they took several weeks to start laying again. I can't say exactly how long but it was at least two months. They did not settle in for a month or so, though, so if yours are relaxed already it could be quicker. Hope so!
