I think around 350o. A little less if the walls are thinner, a little more if nice thick walls. As for time I just let em go until they are tender when I poke em with a fork. One tip. Everything is easier if you line your pan or whatever with foil. I always do mine on a cookie sheet. Usually able to get both halves on it.
I don't do water because I use mine for pies and want as much moisture out of them as possible. After I mash I let that sit in a strainer over a bowl to remove any remaining liquid. I measure out whatever I'm not using right away into what I use to make a pie and freeze in baggies. My girls get the insides too but I don't bake pumpkin for them. I just crack them and let them have at it. I do give them any leftover cooked (and to my pup too) mixed with some rolled oats. Probably be my project for tomorrow since I had to bring all my pie pumpkins into the house after the night temps decided to drop into the low 20's and it's been snowing now for several hours. Think the girls will appreciate a warm treat after they see all that snow when they wake up!
It goes in the compost either way. I like easy.
DW actually just sent me this recently, lol
I always fed them raw to my goats, just cut up in small cubes. Fed the birds the guts. But i thought the birds might like it cooked. I fed them half an apple raw today, they love pecking it.
Same size as my 'big coop' 8x16' all plywood though with a run and some free range (I hate predators..BANG!..), plenty of room for them in the coop when they can't make it out in the winter freeze/snow.
