That's going for about 50 birds. I scatter it around their pasture ... their pasture is bare bones right now. I like to encourage them to go out there scavenging even when it is cold or wet.
The one super authoritative and rather antique source I read about fodder suggested
one cubic inch per bird per day. And so by one measurement I'm feeding several times that amount, accounting for square inches and height of the fodder. But how a person is supposed to measure a cubic inch of something that is several inches tall and can be compressed quite a bit is beyond me. Or was that 1 cubic inch measurement meant for the dry grains the fodder was grown from? Who knows.
I stressed about it quite a bit at first, then I watched them eat the fodder ... they like it and chase after it like any other treat, but they sometimes do move away before it is gone, so I figure they are probably just as self-regulating about it as they are about forage.
The 250ish square inches I'm feeding was originally supposed to be divided up between about 120 birds, but my feeder person can't quite get with that program. It is rye. I send it out when it looks good. The last batch wasn't as tall as previous batches, maybe only 2" of green stuff, but I wanted it to go out. I do skip some days ...
For me this is really a replacement for forage while I'm between pastures. It might be a regular thing in the winter, but I'd prefer to get them rotating through fresh green pastures all year round.
