The baby moo's are looking great! I am soo hooked on mine
How old are your pullets, about 12-14 weeks? It wont be long.
If you are any good with electricity you can make a great one, cheap.
I used an igloo cooler, hot water heater thermostat and a ceramic light fixture.
PC fan and AC phone adapter.
Very much like this one..

I did line the bottom with 1 " patio brick pieces for a heat sync and a water dish.
Put 1/4 inch hardware cloth over it and used shelf liner to protect their feet.
I have also used paper towel.
I plan to add a window this year so I can peek!
I had no problems hatching geese in there last spring.
We do eat many of the roosters. The pullets are very easy to sell usually.
I also offer chicks for sale, but it gets hard to compete with the feed stores in may!
