Are they pecking each other to death??

[Stephine]

Most likely they are pecking them off the heating pad because of space.

Can you get several large boxes and tape them together to make a larger area for them?

I don’t think the area they are in is predator proof, so cardboard boxes wouldn’t do. Though a small wire cage like this is also insufficient... As much as I dislike having chickens in the house, some large moving boxes with a wire screen on top (we use part of an xpen) is really the easiest solution to brooding. Or a coop with a heating pad, but we don’t have electricity out by the coop. I would brood in the house until feathered, keeping them on the cool side to speed things up, and then put them in the coop asap...

I can see overcrowding since they technically need 4-16 more square feet for their age. I am working on extending their space but we don't have the right tool to cut the metal and are going to buy one soon.
Overheating is not an issue. I have a thermometer in there and it is technically too cold. It's been 35-60 in our carport where the chickens are and the heat lamp only warms up the right side up directly under the lamp to 70. That's why I added the MHP. If anything, it's too cold for their age. They don't seem to be too bothered by the cold temp though because I see them mingling about the cage during the day.
I can put her in another section of the cage right next to them! She will be able to see them through the wire. I guess I will have to move the heat lamp so it can be shared between the two sides? Or do I just get another heat lamp?
I didn't know they needed toys! I will gather a few things tomorrow and add it!

Yes, in the short term, putting the offender in the section next to the others is a good idea. But you‘ll have to figure out the space issue at the same time. Adding things for them to do will help, but they also grow like crazy and will need even more space in a week or two... They also need more height than they have in this setup...

Hopefully the OP can clarify the location - I thought it was mentioned the location was in a garage, but could be wrong. Nonetheless, the space is still too small. Separating or punishing birds that are picking at others due to limited space is not productive. Once a top chick is removed, then another emerges and continues the behavior. The birds are not the problem in this situation, it's the circumstances.

OP, is your coop/run ready for these chicks? That is your best solution for them.

I was able to extend their cage to the next section so it is 4 square feet bigger now.
I didn't isolate Amelia.
I added a tub of sand, sticks, and wind treats to their cage to give them something to do.
I let a few of them at a time outside to play every day that it isn't raining or really cold. Finally we are getting warmer weather so I will be able to let them out more. Hopefully that will help.
The cage is in the carport and I have seen animals in there before I put the cage in there. The cage is very secured to keep predators out though.
My husband is still recovering from shoulder surgery (both labrums torn) and thought he would be feeling well enough to build the fence off the barn by now. I have no idea how to build a fence! I told him we couldn't bring chickens home until we had the coop ready but I caved and here we are! Ugh!
I'm going to ask my father-in-law if he can help me build a fence.
I am looking into buying a used ready-made coop until the fence is built.
Thanks everyone for your help!

Hey! Just wanted to give everyone an update in case you are interested. Since building their new home, there hasn't been ANY issues with Amelia, the pecker! I let them free range during the day sometimes, and they go in their barn at night. Here are some pictures of their home that they have been enjoying for the past 6 weeks!

Feeding the chickie babes some treats.

Amelia! Much happier now that she has more space to roam about. ^

Put their old cage in their barn.

I leave the barn door open durning the day and they go back in at night.

Our son, Troy, loves his chickie babes.

Lookin' Good!

Amelia is just a cutie pie!

Great news! Yes, space makes all the difference!

Well done! Happy chickens! Troy is adorable, too!
