Mine aren't laying either.
GLW 5/15 and SLW 7/20 I know they are young for laying still and I have one barred rock also 7/20 but her breed should be laying and is not.
I am just going to be patient and wait it out.
I was misinformed by my feed store that grower and layer crumbles were the same. So I fed Layer which may not have provided enough protein - I am adding cat food to supplement and nolonger offering scratch or treats.
Other than that I just have to wait and see. Many of my pullets are starting to develop very red and pronounced combs and waddles - Not like their rooster - I have one of them too so I know they are pullets for sure.
Can't tell from the backside about dropping vents but waiting
Not about to feel up my girls and try to figure it out- If it happens it will and hopefully I will find the egg!
With you on the waiting game
