Hi. A few weeks ago I got 4 chicks. A few days after I got them I noticed the Jersey Giant, Seagull, has a bump on her abdomen. It's almost in between her legs. It moves a bit too.. Like if I'm holding her trying to look at it it will move down...I'm not sure what it is. She's acting fine. She's around three weeks old. She runs around with the other three, eats, drinks, she's acting completely normal. She does sit down a bit more that the others though. I'm just worried and would like to know if anyone has any ideas to what it could be. Thanks. I'll add pics in a little bit.
