That coop is lovely! My only question is do they feel safe and snuggly with all the windows? Are their roost bars in a quiet dark corner? While we're at it, smooth 2 x 3's or 2 x 4's actually make the best roost bars, chickens don't actually love round bars, and prefer to have their feet flat and their bodies fluffed over their feet.
Sometimes the pullets just haven't taken the time to read the manual -- TLDR! I think Mother Nature - weather, atmospheric conditions, etc. also play a large role in laying patterns, beyond stress. Some pullets (of a breed) will start laying and it sometimes takes weeks for their sisters to join in. Is that because many modern breeds are hybrids? just normal genetic variation? I wouldn't know for sure.
It really seems like you are in tune with your ladies. Have faith, stop worrying, give them to 22 or so weeks before you start to panic. They do look like Reds, who usually lay early, but with all the love and great care you are giving, I'm sure they will be fine. I'm not an expert, I've only had poultry for 10 years, but as a 4-H Leader, I do a LOT of research. I think BackYard Chickens is one of the best places to go for information and advice. Good luck!
