Why give Thomas to someone else ? Because Abby might be a threat to him ? I think Abby needs help, and she's the one who needs to be treated in some kind of a facility. To have Thomas go to someone else doesn't seem to be the solution. Chad is there, he won't let Abby hurt him (and I don't think she would). Though she shouldn't be alone with Thomas. Still, why would Chad want to get Thomas out of the house, now that Ben has been arrested and can't go anywhere ? I realize this is Days, but to have him escape, with the burns he has, would be beyond stupid and unbelievable.
