Help with a neighbors chick
I had something similar happen with the last clutch of chicks my hen hatched. They were the only hatch I didn't give electrolytes to. The one had a big lump on her chest the was see-through(partially) and I got really worried. Didn't do anything and they are fine, healthy pullets and a cockerel. There were three of them. At first I was worried it was a birth defect that I just didn't notice at first, because those were the eggs that had been in the refrigerator for a week, but it wasn't . Maybe it was because I hadn't given them electrolytes...Now all chicks will always get electrolytes. I also gave those chicks medicated chick starter. The only reason was because we couldn't get unmediated. That might also be a reason. I don't know.
What breed is it? I don't think this has ANYTHING to do with it, but I'm just curious. Mine was a cochin bantam cross. All three chicks had the lump, but hers was the most noticeable. .
was the concern it's behavior or the "lump" .? if his only concern was the "lump" and the bird is acting normal there would be no need to treat with Amprolium (corid). Remember the "lump" is normal chicken anatomy.
