HELP!!! Older hens attacking chicks! what to do?

I'm just answering because you haven't gotten a reply. Hopefully someone with MORE experience will come along & add or correct this but

It sounds clearly like they need to be seperated. It doesn't have to be complex, maybe even stretch a sheet attached with clothespins to seperate part of your large run. I would put the hens in the smaller area because I think chicks need room to grow.

You could make a small tractor
You could use the dog crate
You could keep the hens in the hen house & let the chicks have the run

but yes, I think they will pick on them from what I understand and could really harm them. They should be closer in size before introduced to eachother freely... in other words, the chicks should be at least able to defend themselves before you start the beak to beak introductions

 

Was this posted over again...I swear I just left a comment for this one...or am I going crazy? Could very well be!

 

You need to keep the little ones seperated from the older ones. Reintroduce them when they are closer in size. Chickens like to establish their pecking order. They will kill the little ones if given a chance.

I have recently (a month or so ago) introduced my 13 weekers with 8 weekers. It was rough. I made an excape box that the little ones could easily get to but that the older ones couldn't. It worked. With in two days all of these chicks were getting along great and would even snuggle together at night.

Now we are getting ready to introduce this lot to my older lot (25 weeks with 18 weeks). So far there is no problems. I still have the box for the two littlest ones so that they can excape if needed. Odd thing...my buff orps are the one to watch out for. They are soooo lovey dovey to us humans; but watch out if you are a smaller chicken. They are such Dr. Jekyls and Mr. Hydes. I only have three orps and think that is just enough with the 17 others.

If you can divide their home/pen in half that would be awesome. My girls have been able to see each other through the fence. When I fully put them together I will remove a smaller home for the younger hens and the two runs will come together.

I would wait until your chicks are closer to 4 or 5 months before reintroducing them.

Good luck on your chicks.

Double post but I'll link these together so the answers can be all in the same place.
