Precious picture! Relax... you are doing everything well. Chick PROBABLY won't drown but there are tiny waterers for new chicks. When ours raise chicks, they all just stay in the general population....moms are VERY protective and we haven't lost any to other chickens or roo. Have fun with them. (We've gone from a dozen Buffs to 40 hens with lots of breeds and mixes now.)
