Egg shells (used in many craft projects) are quite porous, and will give your paint an excellent ground. Remember however a flat paint will not be very durable (it should not be washed or cleaned) so consider a clear top coat in what ever gloss factor you like. If however if you are asking about the paint finish called eggshell (one having the ability to be gently washed) then it will depend on the age of the "eggshell" paint, the composition of the two (eggshell & flat) paints and the colour of the "eggshell".
If the "eggshell" is older than a year, latex or acrylic based and a light colour, then a good washing with TSP or some other gloss remover, and going over it with one or two coats of a good quality flat latex, oil or acrylic paint should do the trick. Oil paint can be directly applied over latex, acrylic or oil... Latex can be directly applied over latex or acrylic but not oil... Acrylic can be directly applied over latex or acrylic but not over oil.
If the "eggshell" is less than a year old, oil based or a deep colour, then a good quality primer coat will make the job go much smoother. (Note- use an oil based primer if the "eggshell" is oil based, you can then top coat with any paint formula)
