Congratulations on finding a rehabber to take them. I used to try to do it myself, but they know more and have what they need. When I find orphans - even if they are nusance birds - I take them to the rehabbers and give them a donation. I took a batch of babies to one and she had a house full of babies with a feeding schedule and all - she was better equipped and had her day planned - trying to fit 3 little babies into my busy day was much less optimal. I would encourage everyone to seek out rehabbers and have their numbers handy. I always leave their home feeling lighter than air with relief.
I caught the neighbor's dog coming back for his 4th chicken - I wanted to kill him. But I didn't, I put him in my kennel with water and shade until they can come take him home and secure it. I am sympathetic, but my dogs are not allowed to hunt wildlife - I give them dog food. They are to guard against attacks not make them.
