Ours were very slow to start this year due to our unusually cool temperatures. But have now started to take off and produce fruit. We are southern fleurieu.

I plant mine a bit earlier and found that they take a fair bit of time to take off. Plenty of water and a good fertilizer will move them along. I use Power Feed liquid fertilizer and get great results

The first leaves that come out of the seed are called cotyledons. The next set of leaves are call the first set of true leaves, these can take a few days (6-10) to appear. You may need to look at do you have good rich soil, do you water regularly, do they receive plenty of sunlight.

I plan to plant them in a spot with a bag of composted chicken manure in Zone 8b. Any suggestions? Last year my cuke plants were glorious and were started from a packet of seeds. Unfortunately I did not get one cuke. Lots of flowers but I think they turned out to be all males.

Same problem here this year; beautiful leaves, taking over the area on my balcony....but all male flowers!!!!!!!!!!!!!!!! I know with tomatoes you have to get the temperature to drop low enough to get them to fruit, maybe same with cucumbers?

The yellow leaves might be due to too much fertilizer. Try just using one type. They should grow if you are giving them enough water and protecting from very cold nights. The female flowers have a tiny, cucumber shape just behind the flower.
