Thanks @anjovi6 for the update. Sounds like a good plan.

About the oyster shell, i read some threads that they feed their chooks with crushed egg shells as source of calcium.

here are basic needs of various age farm animals and the contents of our feeds we mix ourselves



higher calcium levels in adult roosters dont effect them. Its ok to feed a backyard flock with layer feed

if you are concerned, then give a protein content of 14.5-16% and add oystershell in a seperate feeder that they can control themselves.

we get our oyster shells from "pala-pala"restaurants that cook fresh fish to order.

we buy by the sack - normally between 30 and 80 pesos per sack, depending on location.

we unsak them, dry them in the sun for a few weeks and they are good to go

if you have coastal water and tidal rivers in the region, you have oysters.

it took us some hunting but we now have half a doz sources

you need to give more egg shell than your chooks will produce

Yes that is true. I have asked my wife to save ours and ask the neighbors to save theirs also. I will wash them, store them, then prior to crushing I'll bake them for a little while and then crush them in a mortar. The baking makes them crush into a better consistency for the hens.

Thank Mark,

We are still looking for sources around our area. But so far no luck. The part about the calcium being harmful to roosters came from a paper done by K-State U. There are several post on BYC that is saying the same thing. Personally I don't know. We raised chicken on the farm where I grew up and we never worried about calcium levels and I cannot remember any of our roosters having any health issues.

So you are probably right.

there are many myths on byc

the possible issue is stone formation in the tract that semen travels along

Mark,

I looked for the article last night for over an hour and could not locate it again.
But I will keep looking for it and post as soon as I find it.

Mark,

I still haven't found the article I mentioned but, did run across this one that was quiet interesting.

If I read it correctly a 2% calcium feed would be almost ideal for roosters.

Additional dietary calcium fed to Barred Plymouth Rock roosters reduces blood cholesterol, elevates seminal calcium, and enhances sperm motility, thermo-tolerance and cryosurvivability.

Abstract

Chicken sperm cryosurvivability may be enhanced by manipulating diets fed to roosters because diets modify quality of fresh semen. This study investigated the possibility of added dietary calcium (Ca) improving chicken sperm cryosurvivability due to an elevation in seminal Ca concentration ([Ca(2+)]) and a reduction in blood cholesterol (Ch), which may increase fresh sperm quality, thus thermo-tolerance and cryosurvivability. Thirty 21-wk-old Barred Plymouth Rock roosters were fed diets containing 0, 2 or 4% added Ca for 26wk. Blood [Ca(2+)] and Ch in individual males were assessed weekly. Seminal [Ca(2+)], Ch and sperm motility at 0, 1, 2 and 3h after incubation at 41 degrees C in seminal plasma from males of different groups were evaluated at 28, 29, 30, 31, and 33wk of age upon pooling the samples per treatment during each collection. Also, sperm motility of fresh pooled semen and of frozen-thawed samples, collected at 34, 35, 36, 37 and 38wk of age, were analyzed. From 22wk of age onwards, blood [Ca(2+)] was significantly higher and Ch lower in treated males than the control. Seminal [Ca(2+)] in treated males was higher than in the control during the sampling period, with 4% group being highest, followed by 2%, and control groups, but seminal Ch was similar among treatments. Regardless of the seminal plasma source used, motility was superior in males fed 2% added Ca, followed by control, and 4% group. Spermatozoa of males fed 2% added Ca had the highest motility in their own seminal plasma or of control males. Also, spermatozoa of all treatment males displayed higher motility in control seminal plasma compared to that of treated males. Frozen-thawed sperm motility pattern was similar to that of fresh semen; with that of 2% group exhibiting superiority to that of control or 4% added Ca-fed males. Indeed, additional dietary Ca elevated seminal [Ca(2+)] and lowered blood Ch, which enhanced fresh sperm quality measured as motility, thermo-tolerance and cryosurvivability, especially in 2% group, but not 4% added Ca-fed males.

Here is another VERY INTERESTING article to read. I don't know when it was written but check out the picyure of the brooder and what they are using for a heat source.

Mark, check out chapter 4 on pigs.
