null to 1% purity takes the most time for alchemy... 4 hours easy before you see any difference. That time decreases as they assume one dominant purity. I saw a change from 6 to 7% from unburned garden pot in the pressure cooker in as little as 1 hour (as example); but times will flux to some extent.
Be aware as you get more pure...and/or if you start from a pure state the time for the first change will be exponentially less.
Best to start from at least 1% state for chicks if not more if you are concerned about their survival (and your table/stove not going 'poof')
Old world- rumor was that your feed could affect purity of your produce; but it had to be a magnitude higher than chicks inside. Considering how much feed a coop requires- your feed to unlikely to be anything but tier 2-3 pumpkins... lots constantly.
As we can now find purity turkeys to start- I have not tested whether feed matters. Certainly null feed has not reduced the purity yet. The materials you build the coop out of are immaterial. Was old world- and I have seen/heard nothing to indicate there is any difference.
NOTE: as it is now- you don't need 2-4 coops to develop every element at once... based on hens purity. If feed does matter- that would be BIG news. Do tell!
