help...baby chicken with something in wrong place

[beavers12]

Hi All
I just Got A New Batch Of Baby Chicks...They ArE One Week Old . The Ones Who Survived Shipping Are Doing Great. HoweverToday I Noticed My Buff Brahma Girl Appears To Have A "Mass" Between Her Legs. Like Looking Like A Toddler Running Around With A Full Diaper. She Gets AroundFine, Eating And Drinking Well,Output Seems Normal ....Acting Just Like The Others! I Maybe Could Say She Is Breathing Harder,And Potentially Lays Down In A Little Different Spot ...I Felt It And It's Hard And Maybe Attached, She's Not Thrilled When I Do That. Like Possibly The Back End Of A Keel Bone??? Compared To The Other Chicks Of The Same Age, It's Abnormal.
What Could This Be
How Do I FixI It/How Did It Happen?
Is She Going To Be Able To Lay Normally If/When It Does Heal?
Cull?

Thank You For The Help!

Never saw that before. Hopefully someone who has will answer.

Is it possible she has pasty butt? Check umbilical area to rule out infection.

Rear Is Clear! I'll Check Her Belly Button.
