This question follows on the recent "Is it worth it, financially?" discussion. I am not looking to make money, but I would like to make an educated guess about how much I will be in the hole by . I have searched the forums, but haven't quite found the answer to my questions--and I hope this is the right forum for this, because for me, it relates back to management--sorry if this is misplaced! For those of you who keep Rhode Island Reds, can you tell me: (a) how many pounds/kilos of feed X number of mature layers go through in Y period (NOT the dollar amount)--basically, the feed-to-egg ration for this breed; (b) what is the dressed weight of a 16- to 20- week old roo vs. hen? and (c) silly question...does a mixed-sex batch usually work out 50/50 male-to-female? (What these questions are in aid of: I am trying to figure out whether to get the minimum order of 25 chicks all to myself, first building a much bigger coop than planned; whether to try harder to find someone local to split an order with me; whether to get all pullets or mixed, slaughtering all roosters in the fall, before they get too brash and noisy. Your answers to the three questions above will help me to make these decisions.) Thank you in advance, from an about-to-be first-time chicken keeper!
