What to feed?

Your pullets' diet sounds pretty good to me, and they sound like they're doing well on it. Molting is protein-intensive, so if you wanted to bump up the protein, you could try (for example) feeding chick starter plus free choice oyster shell - chick starter usually runs around 21% protein vs around 16% for layer (you can buy higher-protein layer feed, but I used Scratch and Peck's organic layer as the example).

Some people feed Nutrena Feather Fixer during the molt, and it's around 18% protein. I don't use it, so can't really expand on it. I'm not sure if it's available as organic or non-GMO, either. There are several threads addressing the feed, here's one: https://www.backyardchickens.com/t/820282/naturewise-feather-fixer-pellet-anyone-using.

Laying tends to slow in winter, so maybe your Brahma will surprise you come spring. BTW, I also had a BR once and she seemed crabby most of the time.

 

Hi.

I'm glad you asked!

I have a mixed age and gender flock. I use Purina Flock Raiser which is 20% protein and 1% calcium with oyster shell on the side. Too much calcium as in layer feed (4%) for non layers can cause kidney issues in the long term. That is what is available to me. The important factor is more protein and less calcium.

If organic is important to you, you can use a starter or grower non medicated feed as I haven't found any flock raiser that is organic. The higher protein will not hurt anybody and offer oyster shell on the side for the layers. And the extra protein will help feathers grow in faster. Feather Fixer is a gimmick and just what they call it because it has 2% more protein than their layer feed. The non layers may sample the OS but they won't over dose on it.

Using either the flock raiser or a starter means you won't have to switch if you have chicks in the future.

As far as what you are using for scratch, I would limit it to less than 10% of their total daily ration because those products further diminish your protein level. And corn digest hot, so it may be a good winter evening snack but avoided during hot weather. Pumpkin seeds are claimed to be a natural wormer. And most people prefer Black Oil Sunflower Seeds, sometimes called BOSS.

Best wishes!

 

Some breeds actually require more protein to produce eggs consistently and be healthy. So it might actually help them! The 16% is OK for some light breeds.

As long as you aren't going like 30% protein, you should be good.
