Help!!!! What is wrong with my silkie mama????

My silkie just hatched 9 eggs 2 days ago. She's very devoted and never leaves her nest. While changing water this evening I noticed her beak looks injured but she's in the maternity ward away from the flock. I came out to clean her off and of course she flipped out and fought me hard. I began to wipe her beak and some water dribbled out of her beak then 2 minutes later she pooped a ton of watery poop. No blood or anything odd but it was very watery. She's acting totally normal. Sitting on her babies. Eating, drinking showing them food etc. I did take 3 of her babies the other day because 1 has spraddle leg. Maybe she's stressed and malnourished???? What should I do??
