Nutritionally all eggs are almost identical. If the snake is willing to take them then go for it. Just be prepared for some messy poop. Eggs and fish come out the other end of the snake rather sloppy.

As you are trying to put weight on the snake I would feed it as much as it is willing to eat unless you have observed it to over eat and regurgitate. Give it a little more each feeding until you see it act less "starving" at the end of the feeding session.

Best of luck,
