on partridge/blue partridge its going to depend. If your blue hatched with partridge markings its already got partridge in teh background and is more likely to throw you some partridgey chicks.
Theres so much contraversy about what shade and amount of markings constitutes blue partridge though. I have seen some like the one I call blue partridge from my shipped eggs, it looks partridge except there what would be black in gold partridge is slate at darkest, and the underfluff that would be slate in a gold partridge is a very light blue, and the gold is paler. Then I have a dark blue girl who was solid blue as a youngster, then by the time she was 4-5 months when I got her from the breeder she was getting some serious gold in her neck and crest...now at 7 months shes got definite gold lacing in the crest, neck, chest, and wings, but shes so dark its hard to see definitely, and I have seen 1 or 2 big breeders who say the majorily medium-dark blue based - take forever to pencil/color in, are 'blue partridge' ...
You are likely to get the lesser noticeable blue with gold leakage type chicks from this crossing, but you'll get better ones when you cross back the blue based offspring from the partridge X blue back with each other and/or a gold partridge.
