How many inches of feeder per bird?

I have about two feet for 30 birds. It works for me because its not restricted feed and they dont eat at the same time.

 

Most adult birds are between 6 and 8 inches wide standing side by side, I would just use this as a base depending on your breed of chicken maybe a bit wider like Jersey Giants or a bit smaller like bantams. It's sorta a common sense question In my opinion, not stating your asking wasn't warranted, because you are needing an answer. But that's how I usually try to look at things. That being said my space for other critters is figured like that so why not chickens, shouldn't be much different, the only ones who gets tons of space is the horses because if they are too close the lowest ranked member will not get any food. so my horse feeders are at least 15 feet apart, so a 3 foot wide horse wouldn't work for that calculation.

 

True If I had 24 chickens, that would actually be 12 feet of feeder, I would think they would not all eat at the same time, my girls do seem to want to eat all at once 1 starts chowing then the others seem to follow when they are inside for the day, that does not hold true when they free range, then they just come and go as they please when hungry, and if space is an issue, I surely would think you could go smaller maybe even a few inches per bird, but I seem to always overdue, rather than redo............ so it's a horse a piece.
I seen a really cool feeder idea on another thread that used a plastic I think? gutter with PVC, and he used much less space, here's a link

I think this is one of the better idea's I have seen......... could try something like this, I just may for winter when they are more cooped up, it's awful cold here average zero to 20 below most of the winter and an occasional week of 50 to 80 below with the wind chill, so I'm wondering just how much they might want to go out.
