When you can get the one with the thing on the belly(probably naval where the yolk absorbs) put it into a tea cup--That will let it rest and hopefully let the prolapse to go back up.
I grabbed th ones in the incubator out after further investigation I decided it was best to cull 3 I couldn't watch them suffer.We are keeping one who can't walk well yet but gets around on his own accord even though it's a he. Pictures coming soon.
Ron how is your hatch going.
Keep us posted!
