could Baby Girl have a nutritional defiency or physical problem

Why are you giving them all of these other additions to their diet? Am I understanding that their main diet is layer pellets? If so, and any kitchen additions you give them are less than 10% of their diet, the extras are not needed at all. Especially, the Nutri-Drench and the Rooster booster. Also, the electrolytes need to be reserved for starting stressed chicks, and perhaps summer time high heat stress or when birds are not eating. They should be drinking plain water. While the pro-biotics won't hurt them, they are un-necessary once the birds get an active flora going in their guts. It sounds like you are trying to do everything right and give them the best nutrition possible. I'd like to suggest that you look at the Fermented Feed and Sprouting threads. These feed options will give your girls a nutritional advantage, and actually save you money instead of buying extra products that they don't need. They are most likely not eating the pellets because of all the other goodies you are giving them. While it's fun to see the flock gobble up the treats we provide, unless those treats are provided in a nutritionally balanced blend, (with the correct amount of protein, calcium and all of the other nutrients that make a balanced chicken diet) it may actually hamper their egg production. Of course, you must realize that I am only giving my opinion here.

 

I'd go back to basics, keep it simple:
A good nutritionally balanced chicken feed, always available.
Clean, plain water fresh everyday.
Maybe some treats each day...less than 10% of their daily normal volume of the balanced feed.

I'm not real clear on your total flock population and how they are housed.
You may need multiple feed/water stations if you have some birds hogging the feed and keeping other birds for partaking. Adequate space and ventilation are key.

Chickens like a steady, consistent environment.....changes stress them out, which can cause a plethora of problems. Changes(feed, housing,population) should be done slowly and given time to assess the effect, it can take a couple days to a couple weeks to assess the effect of any change.

After getting them on simple straight forward diet for a few weeks, see how things are going and slowly add other foods if you wish, keeping in mind overall nutrition.

This is the feed regime I have used for a year now and it has worked out well:
I like to feed an 'all flock' 20% protein crumble to all ages and genders. Makes life much simpler to store and distribute one type of chow that everyone can eat and have calcium available at all times for the layers, oyster shell mixed with rinsed, dried, crushed chicken egg shells in a separate container.
The higher protein crumble offsets the 8% protein scratch grains and other kitchen/garden scraps I like to offer.
