Strange lump on front right side of chick

[ShireFolk]

Hi everyone! We recently got baby bantam chicks (assorted) from Tractor Supply last week. This week I noticed a lump growing on her right side. I don’t think it is her crop. She is acting normal, eating and drinking. Any thoughts?

No sure. Could be a fat lump. Watch her and see how she develops. I once adopted a chick that had a deformed leg. She is doing fine.
