Thank you , I bought 5 bb red pullets yesterday to see if I could get a replacement mamma no luck so far.They most likely won't calm down very quickly, sorry. But they'll live. In between their screaming they will most likely stop to take drinks of water and eat food. Then call some more. It's what they're programmed to do, they don't know any better, and it will take a fair bit of being left alone for them to adjust to that instead of having a parent figure since they've only ever known having a mother around, not being motherless like many hatchery chicks.
The more you stress, the worse you'll stress them. They are very sensitive to our body language and tone etc and will pick up on your distress, but they'll misinterpret it as meaning they should stress out too because their adoptive mother is, so something is clearly terribly, life-and-death kind of wrong. The more stressed you get the more they'll scream. It will become a pattern if you're not careful. The more time you spend with them the more they will demand. Even mother hens usually tell them to go get their own lives after a few weeks or months, otherwise they will often just remain with you as perma-babies. That's detrimental to both them and you. Plenty of folks on this forum, who ended up being imprinted onto, start threads asking what to do, quite stressed over their chicks' screaming about their absence. There's generally only two potential solutions for those who don't want to rehome them... It pays to find a replacement mother figure or let them get used to just being with one another, or they can overrun your whole life.
Given the fact that they were raised by a hen and have now bonded to a human, breaking them of the perceived need for a mother is probably easier if you look around for a substitute mother ASAP before those little sweeties become little terrors. They will get louder and more insistent the more often they see you, and since you're the one feeding/tending them, you can't escape this, you'll be reinforcing their bond daily to both your detriment and theirs. Unless you're able to quit your job and make like a real mother hen, that is.
Some hens will take any chicks, if someone is willing to sell you one like that your problem will be solved. Otherwise you should give them some tough love and spend as much time away from them as you can without neglecting them.
Anyway, that's the general case, perhaps you are willing/able to spend the extra time and reckon you can cope with their screaming in your absence. Maybe yours are smart enough and can learn to cope with only seeing you a few times a day, some people find that works for them. I can't guarantee for sure either way of course but chances are, if you're already stressing at the idea of leaving them to go to work, you would be better off weaning them off of your presence as soon as possible.
Best wishes.
