I have Bourbon Red tom X Royal Palm hens, and have around 20 turkeys I'm raising for us to eat. Next year I'm hoping my BBW male will be able to breed the new BBW females I have. If not, he'll be replaced with a heritage male. My 4 Royal Palm hens laid 220 eggs by July 1, when I quit putting them in the incubator, and they finally quit laying, well, yesterday maybe, when someone laid another egg.... They've done great!
I agree that if you have a chicken chick or two in with your poults or an older poult who already knows how to eat, they'll get the idea of what to eat and drink much quicker, but if you remind them by dipping their bills in the water and food a few times, they will usually get the idea.
I raise mine in a rubbermaid-type bin until they can hop out, then they go outside into a big (2X8 or 4X8) rabbit pen, with or without a light, depending on the temperature. Yes, they waste some feed by dumping it through the bottom wire, but I don't have to clean the cage and they are protected from rats and dogs, moisture and mold.
I really like them. They're funny and friendly and pretty, and they more than pay for themselves.
