When to return cleaned up pasty butted chick to mom?

[Bellasmom]

He's been in all morning, he's been drinking, eating and pooping but his little behind is still irritated and pink. When I first took back after he'd dried, they picked at his butt, even his momma and I immediately removed, so how long should I keep him in? He's 6 days old and the hen has had them out since friday morning even with it being chilly. He's in the house in a box with a towel that he likes to hide in, he's only quiet a little, plus I have a towel over the top with it pulled back on one side. Do I need to rig up some type of light or will he be warm enough?

Thanks!

Of course, he's the only one I named when he hatched because he's a yellow chick and the rest are black!

Rig up a heat lamp...your his mommy now.

If momma can be seperated from the rest of the flock and she will leave him alone, fine put them back together. But if she starts to pick at him and he bleeds...please remember that chicks don't have much blood to lose in the first place.

Got the lamp up and running, not as much peeping as he is now settled down in his soft towel. He is doing the normal chick things, eating, drinking and pooping. My dsis is going to take him when he is ready for a new home if he is really a she.

Does this interfere down the road with the ability to lay eggs if it's a hen?
