I got some babies on the 9th and brought them inside to their brooder with water and feed. But I never thought about putting in a heat lamp. I have had them for about 2 weeks now and I was wondering if it affected them in any way?I have alway wrapped a blanket on top of the broader and always had shavings inside and all of them seem to be healthy im just making sure it's ok.
The usual guideline is that they need access to a space that's 95 degrees farenheit the first week, 90 the next week, and it continues to go down after that.
In practice, they usually warm up and then run around and do other things, then go warm up again.
If they crowd together to sleep, that makes them a few degrees warmer than if they were all spread out (but too much crowding can suffocate some of them, so it can be tricky to balance that.)
In MOST climates that we hear about, a heat lamp or other source of heat is required to get it that warm. Air conditioned houses are usually too cool, also. But there are some places warm enough to brood chicks without added heat, at least during some parts of the year--you appear to be in one of those places.
I think problems would usually show up pretty early: constant peeping, chicks not growing well, chicks dying. You say yours are doing well, so I think they will likely continue to do well.
(But if you raise another batch of chicks when the weather is colder, you might need to provide heat for them.)
