food, worming and housing question

I have an opportunity to get 2 emu from a man who can no longer keep them. They are young-- so young he doesn't yet know what gender they are. He hand feeds them, so says they are friendly.  They live with his goats, cats, dogs.

My questions are: does anyone here keep emu with other birds? Geese, ducks, turkeys? What kind of wormer do people use, and how delivered (paste, powder, et cetera) and what is a good feed ratio?

Thanks so much, this was exactly the information I was looking for!

My emus arrive today. The guy who has them is driving them up here. He says they have always been outdoor birds even though they have access to two shelters. It gets cold here-- 18 this morning. Anybody have them in really cold weather like this? There is a large "goose pavilion" kind of like a carport with straw bales along 2 sides (west and south to keep off wind). I also have a barn with a large animal area in it. Should I try and herd them into the barn if it gets minus zero? They are coming from a place about 2 hours south of us. Still cold, but usually about 5 to 10 degrees warmer. He feeds them something called "4 way sweet feed"? Can they have as much alfalfa as they want?

The are in one half of the field-- not a very interesting field, but large. I put them briefly in with my ducks, geese and roosters and they showed interest in chasing everyone. They are still skittish and I"ve taken my two Great Pyrs out into different pastures. Do they every slow down with the chasing of other smaller birds?
