As many have said you have a lot to learn before you commit to a pea.. Also I have to ask how old are you and are you ready to commit to caring for an animal that will live 20+ years?
So hear is a stab at your questions, although I fully suggest you do MUCH more research as most of these questions are basic 101 stuff that would be answered with maybe an hour or two of research on your own...
so first off, our coop is un insulated, but we will put in heat lamps and heated roosts. plus were in greater vancouver so we seldom get temperatures below -7 celcius. its about 10 by 15. is that big enough?
First off I'm not going to get into a debate about coop heating in this thread, but peas are much more prone to frost bite on their feet and toes then other poultry, this needs to be addressed... As for coop size a single male with a train will take over most of that that sized coop in a few years...
also are glass windows okay? ive heard horror stories about peas flying into them
It's glass, it can break you have to decide if it's right for you... If you do keep the glass, it's not that hard or that costly to cover the windows with some wire fence or hardware mesh to help prevent breakage...
so one thing ive never been able to find is male to femalae ratios. id idealy like to have two males. but i dont know how many hens i would need to keep them from fighting with each other, and if these hens would be too many to fit in the coop?
As said above males will fight, really doesn't matter how many females you have, best to isolate or spread out the males during mating unless you get lucky and they get along without killing each other, sometimes they will, but I wouldn't gamble on it unless you have a lot of room to keep their distances....
also, we dont have a run with a roof on top. is that okay? we do have a large yard with a approx. 4 foot fence. if their wings were clipped would that be enough to keep them in?
Without a roof on the run they will get out, and even with clipped wings a 4 foot fence is trivial for them to hop over, even a week or two old chick without fully developed wings could clear a 4 foot fence...
(on the subject of wing clipping we would have to put them in the coop at night. would that be a huge task?) so we also plan on free ranging them. we have 1.5 acres of clear land for them to roam. would that be enough? also we dont have a gate, would that be a problem? our driveway is approx. 200 feet if that makes a difference. another thing
Clipping their wings makes them very domestic and mostly defenseless, they roost in tall trees at night to avoid most predators, clipping their wings removes that ability... 1.5 acres is no where near enough, you best make friends with all your neighbors within say 2 miles as it's not unheard of for them to roam great distances and ravage a neighbors flower garden or roost on neighbors cars leaving a bunch of scratches on the roof...
we have a 100 pound goldendoodle dog, who i can safely predict will try to make friends with them. he is very enthusiastic about it as well. we do have a fenced yard to keep him in though. will this be a problem?
Flip a coin, every dog and bird is different...
the road we are on is a slight concern, as though its not super busy, it is not a farm road. speed limit 70. i would hate to lose a bird. are we going to need a gate?
A gate isn't going to stop them from going in the road, not sure what you 70 is measured in but 70mph, 70kph (43mph) poses a huge risk in itself, and just a hunch but I'm guessing many don't obey said speed limit or will be looking for a pea sitting in the road, so the risk is huge...
one last thing is, i have heard if we raise them from a young age, they will be more friendly, and less likely to go exploring down the street.
Flip the coin again every bird is different, and even hand raised peas are not exactly friendly, they still have a stand off attitude and love to wander especially during mating season...
we would like to raise them from youngsters, but we also want to be sure about their genders, what age should we get them at?
Regular blues can be sexed pretty early... But, you have many more considerations before that...
one definitely last thing is, i have heard they need to be wormed. no idea what that means
Yep, just like most pets they need worming to be healthy...
May I suggest you spend the next 8 months or so researching and reading about peas, come next summer you can make a much more educated decision on whether you are ready or not to commit to them...
