Oops, not sure how that happened.
LOL.... sometimes the quote function does wacky stuff... I was able to interpret it without problem though....
Remember that different styles of brooding all have different benefits and risks..... while I enjoy brooding within the flock whenever practical I do it with the understanding that I may lose an occasional chick to an accidental misstep by an adult bird. We had around 30 broody hatches last year and we did lose 4 chicks to probable accidents in the run, but we also lost a few to unexplained nest deaths (possible suffocations). The up side to in-flock brooding is the chick growing up as part of the flock already and no integration, also this method allows the chicks to free range with the flock from a very young age so fair weather chicks get a great head start. (at least they do for a flock set up like we run). It also means not having to set up as many additional feeders or waterers (though that really isn't much of a big deal to me, but it could be in some set ups) Since I don't use antibiotics with our flock it has been beneficial for us to allow the new chicks to be in the same coop environment and exposed to everything from day one...
Benefits to separate brooding.... you don't have to worry about nest fighting with other hens and 'imposter eggs' in the nest, also a reduced chance of eggs being broken from squabbles with any attempted interlopers, there is a much lower risk of chicks being injured or even killed in an accidental trampling incident and if you are feeding a special chick feed you don't have to try to figure out how to give it to just the chicks. If the hen and chicks are in a more confined area it will allow you to spend a bit more one on one time with them. A down side to separate brooding is having to reintegrate them.
There are many other plusses and minuses to each method of brooding, and when taking these into consideration it allows you to decide where you want to be in your brooding methods.... issues about nesting/brooding time are further effected by the experience and attitude of the hen...
So as you see, it is just something that has to work best for the individual flock and broody and person.... there is no perfect answer
