COngratulations on your new chicks.
You have to be very careful with babies as a dogs(and cats) prey drive is high with small animals. When our chicks were new we kept them in a large plastic tub (for blankets) we remodeled the top by cutting a section out of the top and replaced it with hardware cloth. I screwed it down with washers to hold it on tight as our two cats would sit on top and gaze at the "chicken dinners" below them... As for the dogs we would show them to our Jack Russell while we held them but never put them down in front of her. She would even try to pull the chicks through the bars of their cage by their tailfeathers when we weren't looking. Once they were about 2 months old , out in the run, and could peck back,she had a little more respect for them. We free range our girls daily. Now the JR and our older dog a husky/shepherd mix run around with them and all is good. It takes a long time and daily work to teach your dogs to accept the "hands off" rule. SOme dogs will never get it. You have to be the judge of how much yours can be trusted. Good Luck.
