My chicks are losing feathers and they are not laying eggs yet

[Louhi]

@Louhi are you aware that you do not need a rooster..not even one...for a hen to lay eggs?

I know but I still need them I will be needing them when they start laying...

No only organic food for my chicks ! I'll try to focus on something's that r rich of protein...
I hope they make it soon
Do you know how many days it takes the last this kind of molting
Ps thank you so much you have been very helpful

It's not just the protein....a good chicken ration has vitamins/minerals/amino acids that chickens need to assimilate other nutrition into eggs, especially if you want lots of eggs.

I know but I still need them I will be needing them when they start laying...

Why? Do you plan on hatching out more birds?

Couple more questions that might be pertinent:
What is your climate?
Putting your location in your profile often helps garner better answers/suggestions.

How are you housing these 150 birds?
How big, in feet by feet, is your coop and run??
