Okay, so I know this is a tad specific... But I really want to know what would be an approx. amount of feed for 4 Silkie hens. How many pounds of laying ration would they go through in say, a year? Also, if anyone knows an approx. guide/amount for developer feed, that would be great, also. I am trying to calculate an estimate for the yearly cost of feeding 4 bantam pullets/hens. Also, if anyone knows of any books that might have this info, I'd love to know what they are! Thank you!
