faded comb

[mastermouse]

I have 4 hens just over 1yr old. They stopped laying in the heat of the TX summer and I did not worry about it. However they have not started again and hens in the past did. They have faded combs and are not laying, they have a crust around the outside of their vent, but the vent looks healthy and they aren't showing anyother signs. They are also not 'squating' when I reach for them as in the past. I am sure there is something wrong, but I can't figure out what it might be. Any ideas?

Most likely molt. Second autumn and each beyond is normally when it happens. A molting hen or one not laying for any other reason will have shrunken/pale combs and a small dry vent.
I would quit providing layer feed and switch to a higher protein grower or all flock feed till lay resumes. It has already been a long time getting too much calcium and since they may not resume till after winter solstice, that could damage kidneys or kill them.
