Hi Jen and welcome from me also.
I'm a bit like Elaine with my jams - maybe its the Jam pan!
If I am a bit concerned about it setting, like in strawberry jam, I'll add a couple of grated or chopped green apples and lemon juice. That seems to work for me. Alternatively I'll sometimes throw in a bit of Jamsetta at about half the recommended dose. But the apple seems to work and it does not seem to alter the taste too much when its a small amount of apple compared to the main fruit.
I don't tend to use recipes as such, but do just stick to the ratio of 1 kilo of fruit to 750 grams of sugar.
I've had some come out a little less solid than others, but nothing actually runny.
I've not got around to hot water bathing them yet though, I'm finding that they keep well enough long enough as is (hot jam into hot jar and hot lid on straight away).
And yes, we will be interested to see photos of the chicken project!
