You have a white one too? Now I'm REALLY jealous!
What I do is either wean them off heat while still in the brooders or if not weaned off in brooder I put in a heat lamp in their new quarters for a week or so, to reduce "shock".
I really like summer time brooding, so much easier to manage the chicks.. so hot here the chicks are fine through the nights with no heat at much earlier ages.
Has nothing to do with being a moron, it just seems to me that 10% humidity is way low- with that said I just realized that you live in Arizona so that may be normal out there. My house humidity never gets below 40 so my incubator humidity stays fairly high though house humidity and incubator humidity are going to be different due to different temps. Really wetbulb temp is what should be used. Personally I would look for some deeper containers for reservoirs so you have plenty of reserve- never hurts to have extra depth as the opening is what determines the humidity. That is all I was saying, just went about it wrong and I apologize.
That is a pretty large incubator in your picture. I have been thinking about this 10% humidity and I have to wonder- Is the ambient humidity in the room that low and if so are you getting too much fresh air in the incubator to the point that the temperature doesn't stay satisfied for long (short cycling) and the humidity doesn't get up because of too much dry fresh air being introduced.
The eggs themselves should have produced more than 10% humidity from evaporation alone, especially with chicks hatching as when they dry out they are raising the humidity equal to the moisture they are releasing. So too much fresh air being introduced or too much door opening by the sitter would be my concerns. Wood usually isn't that dry!
You surely have a point, good hens are key to producing exceptional cocks. Will post pics at their next weigh in. Did u use Cornish cross hens in your breeding? If so im excited for you too.
They were chicks labeled as Cornish cross at the feed store, however I think they are the slow growing version, for butcher at 10-14 or more weeks instead of the super fast and huge to be butchered at 6-8 weeks.
The cockerel is light enough to breed the hens naturally.. will find out in a week or so if the eggs are fertile. the pullet still has not laid an egg, her comb has been red for a while and in the last week it has been growing a lot... definitely going to have a NN roo visit her after first egg. Only have one cockerel and one pullet so I am being super careful with them so no weights on them but I did pick up the boy one time recently and he has a massive amount of meat on his breast.
Got down to 38F this morning - everyone was just fine. In fact when the sun came up, all were down eating and drinking in the 39F temps. I rigged a few more wind blocks, and they had a merry little day. (I was home dealing with a water heater malfunction). Several meal worm sessions and me just sitting in the corner to get them more used to me - by the end, a few adventurous Cream Legbars perched on my knee, and one on my shoulder. They still haven't quite worked out how to go to the upper level for bed time (though they sort of start up the ladder) - but hey, it's only night #2. So I needed to put them to bed again tonight (always a little scary for them when I have to round them up, but it can't be helped). I don't want them sleeping on the floor - that's why the current adult Naked Necks are sleeping on THEIR floor, and I won't make that mistake again. I'll just put them to bed up there every night until they can get it on their own. (Expected low 44F tonight, and then low in the 60s, which is what they're easily used to.) @Kev, good points. They've been in a mudroom needing no heat for several weeks, but it doesn't get below 55-60F there, because it's adjacent to the house. Even when it's warmer, I'll continue to put them to bed in the upper part until they learn on their own (for reasons above).
Thanks again, folks!
(They're still getting used to me, so not a lot of great photos yet - soon, I hope.)
