I have my first time flock of 3 chicks. Seems like a special chick has a seriously crossed beak. Started to notice at 3 days old and it is pretty severe but, she is eating like crazy on chick starter. She doesn't seem to like yogurt or any other mash I make her but, seems intent on the crumble. I have been monitoring her breastbone daily to see if she is putting on some weight. Today when I felt it I was alarmed by a lump that I later found out was her crop - phew. But now I am wondering if it is too large or a problem. She held her head up to me today and kept opening her crooked beak. Otherwise she is peeping and has good energy. I will check her in the morning but given she is always hungry due to the longer time it takes her to scoop her food, I would hate to deprive her of food for a day as she seems to need extra to keep up with her sisters. The 2 other birds are now noticeably bigger . Any advice is welcome and thank you to all the posters on cross beaks as they have been very helpful so far.
