I have 4 full grown hens; 5 yr old barred rock, 2 yr old (?) polish and buff brahma, and a 1 yr old mexican fighting hen. They are currently on a conventional lay mash, which I will be changing to organic pellets, free feed. I give them K. show scratch (ingredients below), organic black oil sun flower seed and regular scratch daily. I also give them yogurt when I have it, which is almost daily, and fruits and veggies. Mealworms a few times a month. All are in good health, except my barred rock, shes been sick since she was a chick, but shes still alive out of my original 4. Shes a rather heavy bird, and has arthritis which she is getting pain meds for. Now I have 6 2 month old chicks; 2 light brahmas, 1 black langshan, 2 wynadottes and a cuckoo maran. They are not in with the older girls yet, but will be put in with at least the polish and buff brahma, possibly the MFH and barred, if they tolerate it ok. My barred is top hen, but old and I dont want to hurt her, and the MFH thinks that she is a house chicken and people are her flock. Daily the chicks get 2-3 cups of organic chick starter crumbles, 1/4 cup Pelleted Grain Ration (Dynamite, Inc), 1 tbsp Zoo Formula (Dynamite, Inc), K. Show Scratch, regular organic scratch and black oil sunflower seed. They get veggies and fruit and I WAS giving them yogurt until I realized it might have too much calcium? They dont get ay scratch or seeds until afternoon now, I realized it was too much "candy", and corn creates heat which its been HOT here. Now I am worried about my black langshan, I can feel her kiel really easily. I dont know if this is because she is a very light bird, always has been, or if she is actually sick? Their organic crumbles has DE in it, so I am not worried about worms. Are they getting enough fat? The PGR by Dynamite has a very high quality fat content, but the measurements are for horses. Is all this too much calcium? My Dynamite nutritionist said the zoo formula should be ok for chicks, but shes a horse/dog person and tried to give me the best help she can when its in regards to other animals. K. Show Scratch contains: calf manna, black oil sunflower seeds, whole oat seeds, scratch and...ugh I forget what else. Just picked it up, its supposed to be good for their feathers/show chickens, but I am leary because of the calf manna.
