I think, this is a context free language. The Context Free Grammar for this would be: $$ S \rightarrow aSd\ |\ B\\ B \rightarrow bBc\ |\ e $$ Where $e$ is the empty charachter. You can arrive at this by looking at a similar Language which has an easier to guess grammar, $L^{'}=\{a^{n}b^{n}:n\ge0\}$, which has the grammar $S^{'}\rightarrow\ aSb\ |\ e$.
