no, not important - I just alternate between the two for a change really for them. I guess I look at things when I think about my greys eating the same thing every day of the year, how boring it would be for me! So, try and give them a variety too, with things - just my personal preference
As long as they are getting their veggies, its fine - I don't cook the hell out of the veg, as it would destroy the nutrients - I steam it a little for them
