Pekin bantam hatching eggs

[Graciepowell_09]

Hi anyone ,
I recently bought some pekin bantam fertile eggs for my hen and she has been on them for 21 days today ! I candled one a few days ago and noticed flickering like a candle , some of them have nothing and some of them have something . There is no piping yet , should I be concerned. I searched about it and said they may take a few more days if they were posted . Just looking for someone with experience.

Thank you Gracie x

At 21 days the eggs should appear 'solid' upon candling. The clear eggs never developed. Give them time, and good luck for some hatching.
