My girls aren't laying?

[MolliMonster99]

Hi everyone! I have 5 ISA brown hens, 6 runner ducks and 2 cayuga ducks. 2 of my chickens no longer lay eggs due to old age, but my younger 3 turn 1 this month and I've noticed for the last week or so they haven't been laying? I have also noticed their chests are looking a little patchy? It does look like there are new feathers trying to come through, so maybe they are molting? Would molting also be the reason why they have stopped laying? They stopped during winter, started to lay again around February, but as I said earlier, the past week or so we've found nothing!

Also, my 3 female runners and 2 female cayugas haven't started laying either. The runners stopped laying in winter and just haven't started yet, whereas I got my 3 cayugas in January and they haven't given any eggs while I've had them. They are all a month or 2 from turning 1. Any advice would be great, thanks!

Hidden nest?

Hidden nest?

We've looked all over, but I will have another look just in case. They have 2 nesting boxes in the coop, but there is also a box in the run on the table they sit on, but that is also empty.

i have one that wasn’t laying. I’m very new to chickens and didn’t know I needed to add oyster to their diet. if they don’t have enough calcium they won’t make eggs. I started drying out their used egg shells and crushing it up for them as well. Seems to be working. You may know all this, but if you don’t you know now.
