Uggghhh, what's wrong?

Even if your temperature was way off, as long as it wasn't above 104F, you would still see development by day 7. The humidity won't prevent early development. If the eggs were under a week since being laid, that pretty much leaves fertile yolks as the problem. The issue could be either nutrition or the rooster himself. This time of year, roosters need photo-stimulation just like the hens to be productive. In Florida that shouldn't be as big of an issue as farther north.
How old is the rooster?
What makes up all of their feed?

Well I've got all five of my fuzzy butts trimmed. Lucy, my buff, and BooBoo, my black, we're not happy campers, Splash, my partridge

Sorry hit wrong button. Splash, my partridge roo, didn't mind at all. Now I'll wait and try again.

They are almost 9 months. They are on layer feed, and usually a treat at end of day.

They also free range 4-5 hrs a day.

The Roo & chicks shouldn't be eating layer, from what I've read, may cause liver/kidney issues. Have read that others feed Flock Raiser, Multi Purpose, All Flock etc ... I can keep only 4 - 6 chickens, a 50# of Chick Starter lasts forever. Now I start my chicks off a small bag (10#) of Chick Starter or a month, then switch to Flock Raiser & Oyster Shells in a separate dish out when they start laying.

Depending on the size of their range and the quality of forage, I would expect good supplementation this time of year in Florida.
I usually bump up nutrition a couple weeks before I start collecting eggs for incubating.
Layer feed is adequate nutrition for production of eating eggs but not necessarily to nurture an embryo to maturity and the strength to escape from the egg.
I don't think that is your problem though. Your eggs aren't fertile to begin with.
Your rooster is in a good age range for high fertility. You may need a new unrelated rooster. For the time being, I'd add a couple hours of light on him to see if you find halos on the yolks.

Trim your rooster so his bottom looks like he's monk, basically a tonsure cut and see if things improve. He's not going to be the most fashionable thing but you should get chicks.View attachment 1598686

What about the girls don’t they get trimmed too?

I don't have any chicks right now, when I do they will be on starter til they are old enough. As for my roos (I have 5, not all together), they are all eating the layer, some for a year, I've had no problems. Where did you read that? Do you have the link? I want to read up on it.

Well let's see if the fuzzy butt trim, (boys and girls), helps out any. If not, I'll see about getting my friends silkie roo for a week. If he's willing.
