Iron Farm mechanics

Hey,

I've made a couple iron farms before in much older versions but this is my first time making one from scratch with certain considerations and just wanna check a few things before I start.

- Java, server is 1.21.10 but may get updated, don't foresee the update changing anything - I'm building in the sky above a current mostly flat village dead on sea level

I'm just looking to check:

- I've seen mixed answers for distance from the pre existing *actual* village. Is ~50 blocks up (with killing chamber @ ground) sufficient to not have problems? - does java still load chunks in full or has that changed at some point? I.e. should it be loaded whenever I'm in my villiage anywhere or is there a more spherical render area now? I ask because most my memory is from before the caving update, and chunks are much taller now lol - nothing I've seen mentions this - but presume husks, drowned etc act identical as far as iron farms are concerned, yes? I've seen pillagers operate differently but tbh I don't think I want to stuff around with those guys.

Cheers for any help! I probably won't reply for a while as I'm typing this before bed
