Why aren't my ISA brown hens laying??

Quote: Not sure why you would need a heat lamp with the older birds.

Agrees, they do look like they may be molting.

This is good place to start reading, tho some info is outdated IMO:

Might consider using a higher protein feed for both the babies and the older birds...with oyster shell on the side for when they start laying again.
I like to feed a flock raiser/grower/finisher 20% protein crumble full time to all ages and genders, as non-layers(chicks, males and molting birds) do not need the extra calcium that is in layer feed and chicks and molters can use the extra protein. Makes life much simpler to store and distribute one type of chow that everyone can eat. I do grind up the crumbles (in the blender) for the chicks for the first week or so.

The higher protein crumble also offsets the 8% protein scratch grains and other kitchen/garden scraps I like to offer. I adjust the amounts of other feeds to get the protein levels desired with varying situations.

Calcium should be available at all times for the layers, I use oyster shell mixed with rinsed, dried, crushed chicken egg shells in a separate container.

Animal protein (a freshly trapped mouse, mealworms, a little cheese - beware the salt content, meat scraps) is provided once in while and during molting and/or if I see any feather eating.

Yep......I just frown at the links provided as a way to leave answers....Only my opinion, but if uncertain? The OP is only looking for real answers and not guessed info......

Was not stepping on toes....Just stating....

Cheers!

No worries about stepping on toes here.

Can you elaborate as to why my links aren't just a way to support what I believe were the real answers I provided? And that they were not indeed including scientific studies that make it NOT guessing? I'm not asking to be ugly but as a true attempt to find out if the answer I provided was incomplete? I always felt like links were a way to help provide more detailed answers when I saw others include them and that doing so was a skill I have been working hard to achieve...

I am a person who is open to learning new things, so I want to know what it is that's throwing you off about them.
