Do you happen to remember the egg size? Her first was 36 grams. I haven't weighed the other two but if they're any bigger it's not by much. Did they eventually lay daily? Lagertha is still every other day. It's fine, but hard to gather an ideal clutch.
I didn't weigh them. They were quite small, though. Mine generally lay for 3-5 days in a row and then take a day off. They are really good layers for about 6 weeks and then they go broody. They rival the silkies with how often they go broody. I haven't let one actually hatch eggs yet, but I am hoping one of mine will oblige me at the right time for the HAL so I can give her a try.
