Thank you for rescuing this sweet lil guy.

Have you tried offering him treats to get him to come close to you. Put a few treats on the floor that will lead to you, then hand feed him the last treat.

He needs to be walked other wise he will start using your entire home as his toilet.

I would hold his lead in one hand and a treat in the other hand offering it to him, when he comes to you pick him up and give him the treat, put his lead on then give another treat then take him for his walk giving him a treat or two while on his walk.
It is best to keep him on the same food the foster mom had him on, he is going through many changes right now and changing his food will cause him stomach issues. Try mixing the chicken in with his food, hand feed him if you have to. In a week he should be more settled in and a slow transition can be made.

It will be trial and error as to what food he will like.

Hopefully other members will chime in with suggestions and advise.
