commercial brown layers VS australorp black VS light sussex

[aart]

He is insane. I was just informed that he gave a therapy for sick dogs to a sick chicken of my aunt.

Well...many off label meds are used for chickens...always get details then do your research and decide for yourself.

if they are all in free range conditions and low protein feed the black Australorp and light Sussex would lay more than a COMMERCIAL layer because they would have better foraging abilities and would get more protein

Ohh!!!
An interesting option!!!

 

[Mitsos Lamprogiorgos]

You mean that the red sex links can't forage as much as the black australorp and the light sussex.
It could be true!!!

Heritage breeds must take their up sometime!

Maybe, with a commercial bird that had been raised in a cage....
.....but if all raised together from day olds, not so sure about that.
Folks have ranged CX with layers from hatch and the CX foraged just fine,
not that it would meet the CX nutritional needs as well, but still.

 

[swampchicken 15]

you are correct

We have 2 red sex links, they lay almost EVERY SINGLE DAY. Not even time off for molt or winter, nothing. And they lay an Extra Large lovely brown egg. Can't even close the egg carton on them most of the time. They are also amazingly docile and friendly. (Let my 5 year old hold them and go down the slide)
We also have a Black Australorp. Her eggs are medium with a thinner shell and she is the poorest layer of my current flock.

Are the layer pellets the basis?

I asked some chicken keepers in Greece and they told me that red sex links are the champions only if they are eating layer pellets.

Even minorcas lay more without the help of layer pellets.

'Layer feed' is not going to make birds lay or not.

It depends what's in the feed.
learn to read the fine print on the nutrition tag sewn into bottom of bag,
more than the pretty label on front of bag.

The big thing with layer feed is it's higher calcium content,'which of course they need to make shells, but calcium can be provided in other ways. Layer feed can be lower in protein.

What kind of 'seeds'?
There's a lot of things that affect egg laying, diet can be number one.
I'm betting those 'seeds' are not enough nutrition for the high production birds.

Also, where did he get the birds, did they all start as day old hatchery chicks or....?
How long has he been conducting this experiment?

He's preforming an experiment of sorts, but how he designed and facilitated that experiment could really skew the results.

You just said "not enough for the HIGH production birds".
Maybe you just said that they need higher density food than the heritage birds.
Point of lay pullets from one of the biggest companies in the world, maybe the biggest.
Don't want to reveal the name.
