Newly Seeded Alfalfa - Timothy - Orchard Grass

I am in BC Canada and we just seeded a field last fall in September.   We seeded with a mix of Alfalfa - Timothy - Orchard Grass.   

 

I see the grasses coming in nicely but I do not see the alfalfa much.   Is this normal for a newly seeded field?   Or should I be concerned the winter may have caused issues with the alfalfa?   I see it in areas pretty good but its scarce.   

 

Any tips on getting this newly planted field growing better please let me know.   

 

Thanks
