This is such a frustrating problem! Why aren't there better dryer designs? Does anyone make a decent vent hook-up, or aluminum hose that stays in place and don't fall out in the back of the wall? Anyone have something that actually stays in place? I don't want laundry detergent scented air inside the house.
I haven't had a problem with thisThe trouble you may be having is that since the vent through the wall is behind the dryer, you can't easily line up the dryer vent and the vent through the wall once the dryer is partway in placeWhat I have done is get some expandable aluminum ducting, attach it to the wall vent and the dryer while it's expanded, then push the dryer into place until the ducting has squashed up as short as it will goIt's bit tricky to do, measure carefully, but it worksIf, on the other hand, you can get at the back of the dryer easily, then use aluminum duct tape to seal the edges where the ducts meet, the very shiny kind of tape made for heating ducts, not the fibre-based stuff we all use for everythingIt will take heat, is very very sticky and it's like tin foil, so you can get it to fill little spaces and mold it around edgesBig hose clamps will do the same thing.
Your best bet is to cook the chicken according to the size first and make the stuffingWhen the chicken is about 3/4 the way done add the stuffing, this keeps you from getting salmonella poisoning, and keeps the chicken from being raw near the stuffing.
