Fodder system for small farm

I have 2 calves and 29 chickens I want to feed them fodder... What are your ideas... I'm height challenged (short female) I have a 10 x12 feed room.. That will have good roof, water and electric by spring.. I want to use water responsible and thrifty... What opinions on types of seeds best, worse, best flavor and so on... Should I buy the trays or have you found a better way... Thanks I don't want to waste time and money reinventing the wheel..

I am also looking into building a fodder system for my 3 cows, numerous chickens, and 2 pigs. I have been doing a lot of research and planning for how I want to set it up. So keep in mind this is coming from my own research, not coming from a point of experience.
I have determined that for large scale fodder systems (like for cows), instead of trays, look at using a roofing panel (like in this system here:  https://m.youtube.com/watch?v=dJVkhns1rhs)

All I have seen in regards to thrifty use of water is that reusing water often causes mold after one or two uses.

As for seed type, I plan to use barley and wheat due to availability and a lot of people say those are quite palatable.


Anyways, hope that helps!

Thanks I watched the video.. I like the system... I guess the water could flow to outside for animals to drink then flow to ground..

Instead of using bleach could I use vinegar?

I'm not sure if vinegar would work, you will probably have to do some trial and error....I know bleach is not a good product when we are all trying to grow organic animals.
But definitely using the waste water for animals would work great! I will keep that in mind when I build my fodder system.
