Don’t get me wrong the heat plates are great, but just not for new quail. I often intro my buttons to slightly older groups, as I sell them and condense them into new groups, and I use a heat plate for that. Last weekend I put 2.5-3 week old chicks with a few 3-7 week old males. I set up the plate at a slant, the smaller chicks can easily fit under, and the big ones can wedge in at the sides, but not go all the way, this gives the younger ones a safe place to hide and still gives them warmth, and the big ones get used to mingling with them, after a week or so, you can’t tell they were ever strangers, I haven’t had a single injury this way so far. I also use the heat plate quite often in what I call “sick bay”. It’s great for older chicks or birds that are ill and just need a bit of warmth and safety without glaring heat beating down on them.
