Yeah. It just seems like if the ambient air is very warm, a lamp wouldn't make as much of a difference. May here is usually 70s or 80s, though occasionally 90s. I've only received chicks in summer (I'm a teacher, so I work fewer hours during summer because, contrary to popular belief, we aren't paid during summer break). Temps here are usually higher than what the gent in the video says chicks need!I have to imagine so, which is why some hatcheries don't really do winter orders or only do large orders, where the sheer number of chicks in the box would keep them a bit warmer.
All my chicks have come in May (just kind of worked out that way with getting the breeds I wanted), where average temps range from mid-40s to maybe 70 on a good day. So that does have some effect on timing as far as when they get their first day out of the brooder, or when I take heat away. Like with my last batch I delayed removing their heat for 2 days due to a big storm going through the area.
But most hatcheries ship from the midwest and ship overnight. So what he says makes sense, esp given what others brought up about the fiasco at TSC with those awful brooders they tried. My next order is coming in May. I *might* get a lamp and use it if I feel the chicks are poorly upon arrival. I have always thought lamps were less "natural." Idk.
