We have gotten pullets in the past and would have done it again if there would not be the shortage in my area. If you get pullets do you not have to invest in a brooder, light, food etc. Another advantage is you get faster laying.
We raise from 1 day old chicks this year and even getting 1 day old chicks is. We were lucky that we only got the light and feed. With 15 chicks have we gone through 5 bags of feed already. Since we raise meat rabbits did we already have tractor etc.
$14 for 19 week old pullets is a good price and they would be ready for the coop. What is best depends what is important for you. Maybe prioritize what you want (age, breed, equipment, feed) and then make the decission.
