Yay! Good for you. I'm sure he'll turn into a wonderful doggie for you guys.
As for the fear issues, if he hasn't been exposed to a lot of different things as a pup, he's bound to be quite cautious now. I would recommend not pushing him beyond his comfort zone - don't force him into situations that he'll find scary and can't get out of - you don't want his negative feelings about the 'scary thing' to increase. If there are things you need him comfortable around, expose him gradually and always allow him to end the interaction if he becomes uncomfortable - keep it positive.
Giving food to creatures is a very primal way of showing you care. You can take some of his daily food portion and carry it around in your pocket and give him treats throughout the day whenever you find him doing things you like (such as paying attention to you, sleeping on your porch, being calm around your chicks, anything you'd like him to keep doing!). He'll soon become very attached to you guys and training him will become much easier.
You mentioned he 'ran out of his collar' - is it too big? If you don't want him roaming, you might have to tie him up over night. If that's not possible, or until you get a new collar/whatever maybe get your husband to feed him his morning portion of food by tossing it in the grass for him to search out. It'll take a while and it's mentally stimulating/tiring so he'll be likely to eat and take a nap until you get up and about.
Anyways, I hope all goes well and hopefully my advice is useful. Let me know if there is anything else!
