I pull mine at about 3 weeks of age so that 3-4 feedings is usually enough and so that the pins cover them and a heat lamp is not necessary (though I try to keep my house above 75F at ALL times, easy for me living in AZ). For larger nest I tend to pull them 1-2 at a time, depending on hatch dates.
You always want to see that the crop is EMPTY before another feeding. Can't stress this enough.
With that kind of schedule, obviously as soon as someone gets in the shop, once early afternoon, once early evening & possibly one late night. This is dependent upon the babies & how soon you pull, you could probably get away with 3 feedings. I tend to do the last feeding as late as possible & have actually gotten up at a crazy hour if I check on them during the night & find them hungry (this is only the 1st week that I've found this necessary).
I was taught by a lady who's raised just about everything, Cockatiels to Macaws. I highly recommend on Amazon Zupreem Embrace Plus handfeeding, the Kaytee brand wasn't my favorite. Def get 5+ lbs, you'll need it! Make sure to make it fairly thick & def follow the directions about letting it cool, it thickens within 1.5 minutes. If babies crops empty too fast, you may be making the formula too thin & if they're slow you might be too thick. They're are techniques out there if the crop doesn't empty! DO NOT PUT NEW FOOD on a full crop.
For your staff, I would suggest a digital instant thermometer. They're about $8 at Walmart, and babies must be fed 100-105F. Also, I prefer the baby syringe they sell for $2, I've never been found of the spoon.
Good tip: have your baby food mixing mini bowl & a bowl slightly larger. When the food has cooled to the right temp, you can put very hot water in the larger bowl & set the food bowl in it to keep it warmer longer.
There's lots more but I'm off to work......a double shift so my lunch time will be feeding them & my hubby may do a feeding for me.
Best of luck! Watch those videos!
