Keets get chilled and die very easily so you have to make sure they can't get into their water and play. I lost a bunch of keets last year when my grandson was trying to help by putting a bowl of water in the keets brooder. 7 of them climbed into the bowl and then got out and chilled. All 7 died.
They're also quick little buggers! I mean super quick! They move a whole heck of alot faster than baby chicks, ducks, and geese. LOL
While opening the top of my incubator, they were running all over the place! It was hard to catch them!
Also, their legs are very delicate. If you drop one or they fall, they'll break a leg and more than likely not recover from it. They're delicate little things in the beginning but after about 6 weeks, they get strong and hardy.
I love my guineas. We call them our Goonie Squad. They come up to the main house every morning to get treats from me. (cause mom spoils them LOL)
And they are great for tick and other bug control. We have had very few tick incidents this year. I think the number is 2 and we have 35 acres of land. So I'm not complaining.
Good luck!
