Is this a fertile egg?

[ForeverFactor]

I found one of my young hens has made a little nest she hid and has been sitting on them. Since our rooster is young and she is also I wasn't sure if they had gotten things right yet. Does this look like a fertile egg? It seems like it to me but I might just be getting my hopes up.

Yes, it's fertile.
How old is the pullet? What size are the eggs?
Are you planning on letting her set?
Small eggs = small chicks = potentially weak chicks.

She is about 5 months old and the eggs are actually pretty small. I grabbed one of the eggs and she took off so I don't think she is super dedicated to the idea yet. As soon as I grabbed the egg she ran off pretty quick and hasn't gone back to her nest yet ~15 minutes. I know yesterday she was away from the nest all day since I didn't let them free range so she didn't sit all night. That said today I let her out and she ran frantically to the nest which is how I found it. If it's likey the eggs won't hatch successfully I think the best idea would be to take them and let her hatch some eggs when she is a bit older.

How much of a chance is there that the eggs are still viable with having not super frequent care and cooler nights in the 60s? The days have been in the low 90s and there have been at least a few days that I'm sure she was giving them most of her attention. Is it too risky to let her have them at this age?

It's not so much her as the eggs themselves.
She also doesn't sound fully broody. A truly broody hen/pullet is on the nest all day and all night only coming off once a day to poop, eat, preen, stretch and maybe take a dust bath.
You can candle them to see if there is any development. But if she isn't committed, there is no point in leaving her to set. And it sounds like the nest is not in a safe place to for her to set for 3 weeks.
