Bhai Mashallah is setup par mujhe kisi b chez ki kami nahi dikhi, all goats are well fed with food and necessary nutrients. What makes you think they are not getting necessary nutrients.
Patt matlab jisne abi tak ek baar b bacche nahi di. Mostly 2 daat ya ek saal ki umar ke baad bakri ko load karte hai tab tak bakri ko patt bulate hai, hope this helps.
