Mothers day and baby chicks

I didn't plan for the chicks to hatch on Mother's Day, but it seems fitting. Yesterday, I could hear peeping coming from under Goldie, when I would listen carefully. I read that you could hear them before hatching, but was still surprised. Today I lifted her up (quickly and gently, and yeah I know I shouldn't) and found four hatched chicks. This one was already dry and didn't have a milk tooth. Maybe she had already hatched yesterday, and that is what I was hearing. Three more were brand new, wet chicks. One doesn't look like it's going to make it, but maybe it had just hatched and weak from the fight with the shell. It's been nerve wracking not being able to see what's going on.
