I am not a total 'newbee' to chickens but I have so much to learn. Does any one make their own chick scratch ? I start my babies on medicated crumbles. Have been feeding the older girls crumbles. Got the wrong feed one day which was scratch, corn, barley, milo. Now they won't touch the crumbles. The problem with the scratch is they won't eat the milo. I am thinking of making my own scratch ~ cracked corn, barley, and crimped oats. I also read folks talking about 'grit'. I have never used grit but I do use crushed oyster shell. If it is not available I can really tell the differance in the egg shells. Lemmeknow ya all's experience please.
