Its not normal, could be injured or infected,
But tge breeder should not sell unwesned babies thst yiung!!!! So many die when they go to a new home as unweabed babies,
We end trying go help people keep their unweand babies alive and most die
I would nit buy a chick from this breeder! He us just spitting them out as fast as he can to get more money. Babies should only be sold after filling feathered sbd weaned abd esti 100% on their own
