I feed mine a mix of lay crumbles, scratch and free choice oyster shell and alfalfa hay for calcium and if I get one lay soft eggs she gets a human calcium pill every other day for a total of 3-4 doses.One of my leghorns were laying really soft shell eggs or ones that would break really easily. Someone told me to put te calf manna available as free choice and the ones that need it will eat it and the ones that won't will not eat it. Only a little has been consumed and I've kept it on the bottom story of the coop so it stays dry and out of the way.
He wasn't a super special bird, just one from tractor supply so I'm not certain if their supplier vaccined them for Mareks.
I feed them in the run because I don't like putting food in the coop. Is flock raiser a good feed for all of them? I have mostly 12 hens a large fowl rooster 5 bantam hens and 2 bantam roosters.
