Then that would be different from dogs, goats, horses, donkey etc who's winter coats are brought on by lowering temperatures and come springtime/summer shedding? Genetics, breed notwithstanding.
I'm not sure what triggers shedding and winter coats.. some animals get them and others don't.. is it light related, is it temperature related or is it a combination of many things humans can't detect including individual hormone levels.. Maybe temperature and light AND even nutrients.. reach a certain level combined, blah blah blah (only meant my questing goes on forever and not as rudeness).. always AGE/gene related... I
don't know, I think genes is always at play.. and I think it's a fascinating discussion! But definitely things are not equal across the board between species.. we don't even have the same digestion
But many people have observed:
Chicks raised in a constant warm temperature grow feathers at one rate.
Chicks raised with a large cool area and a single warm spot (heat lamp, heat pad, heat plate) grow feathers faster.
In each case, the chicks are typically provided with free-choice food, and they waste enough that any differences in food consumption are not noticed.
All I can tell you is I have raised hundreds of birds.. from my own stock in the varying setting you describe including brood's.. and I saw ALL the feathering differences take place in ALL the settings.. fast, slow.. not impacted by.. I think too many folks are reporting too small of number with too wide a range of genetics and limited control groups for comparison.. for there to be any actual correlation taking place.. What I've seen personally says a warm spot when needed, adequate nutrition.. and everything else is genetic..
So I'm saying show me study using a large number of the same age and breed birds on the same feed and husbandry routine.. constant temp verse broody type/ warm up area.. where the birds that had *cold areas* actually have better feather quality and growth rate.. Not this anecdotal stuff from a few hatchery birds under a wide range of possible setting not taken into account number of sleep hours etc..
Using daylight lamps, dark lamps indoors/outdoors, summer/winter, broody/brooder.. You do YOU.. That's not my experience.. and
individual genetics is the biggest factor followed by nutrition.. EVERYTHING else is gravy.
A place to warm up with something cooler however cooler that may be.. even snow.. is the most natural at a young age. At an older age.. temperatures tend to stay season constant with daytime high and night time lows.. While I agree with it being the best option I'm saying the claims of it
growing feathers faster are PURE HOGWASH.. and I don't mean people are liars or even wrong about what they observed.. just that MY wide array of experiences (which I still consider
very limited) does not agree with that take.. having done the experiment using the different set ups and different breeds. I'm calling it limited perception on those who perpetuate it..
I've tested different protein levels, different brooding methods, different breeds.. across the board.. I know I take many hard lines.. but I am here to learn.. so please show me something documented if you can find it that shows such?! Sincerely.
