Can you clarify? Prod RIR or HRIR?Quick question here...how do the SFH lay in comparison to Rhode Island Reds or Barred rocks ?
I can speak to the RIR and SFH, but not the Barred Rocks.
I have both Production RIR and Heritage RIR... big difference depending on what your goals are.
If you are just looking for egg production, go with the production reds. But if you're looking for a true dual purpose heritage bird, then HRIR are the way to go (they will lay about 100 eggs less a year but will live 3 times as long).
So... that's another consideration... eggs produced over their lifetime? HRIR will still be producing eggs when they are 8, 10 or even older. Or eggs produced each year with a shorter lifespan? Prod reds will peter out after 3-4 years but produce a lot during that time.
Once you determine which type of RIR you want, then you need to look at lines...
If you want eggs fast... production reds will do that better than any other breed I've had hands down (they have a little leghorn in them and will really produce)... but they will really drop off after the 3rd or 4th year.
With the HRIR, different lines have been bred for different traits and many of the HRIR do not produce many eggs. I chose the line I have for overall structure, longevity and egg production... egg production was important to me, but it is not to a lot of folks who have HRIR and show them.
There is a guy on the HRIR who is doing a bloodline comparison on his webpage... if you really want to get into the nitty gritty of HRIR, check out his webpage with all the various lines. Very informative.
That was more than you asked, but a quick explanation. The SFH is a totally different type bird than either the HRIR or the Prod Reds. Hard to compare. Their eggs are not as large as the RIR, they will not produce near what the Prod reds do, probably comparable to the HRIR although I have not done an exact comparison (Again, so much depends on the lines).
Hope that helps.
