chickens missing rear ends?

The past two day Rebekka has been to the chicken house in the evenings to feed (her twice a day chore) and has found two chickens each day with their rear ends missing. These are the ones in the chicken house about 2 1/2 months old). Their side did not get damaged in the storm. Are they doing this out of bordem as there is no whole for a oppussm (had one before that did that). Hubby said we were going to add some fencing to the front of the coop and let them out a little more and give them a little more room. Does any one have any suggestions as to what to dowith bored chickens?

They will peck each other out of boredom and if they are too crowded. I have known people to put "chicken playgrounds" in the chicken yard. The chicken swing is fun for them, as are balance beams/perches at varying heights.

Try feeding them more protein. With the addition of meat to their diet they usually will quit pecking at each other. I have found that works as does just a lot more space

They have a bigger room than my bedroom. lol What kind of protein do I need to feed that will be good for them.

We always just through in some raw ground meat. Just a little bit everyday at 1st until they quit pecking at each other and then we cut it down to once a week. Once they start free ranging we cut it out completely. They will get bugs and such on their own then.

Do you have any raw milk? We give extra milk to them sometimes.

As far as bored chickens... let them take dancing lessons!!!

Black oil sunflower seeds or even eggs are great sources of protein.

They did better today. Didnt lose one. I fed them cabbage leaves, apple peels, a little hambuger meat and some fish. I am going to go get some raw milk this week if I am able. I played clean out the freezer for the pigs and chickens today. They loved the fish best I think.

Am I understanding correctly that they don't get outside much? If so, they'd probably love some grass clippings.

I am happy to hear they are doing better today

We feed gras everyday. About a 5 gallon bucket for each part of the house (two being used) Their chicken tractor is not done yet due to Hubbys Grandmother getting sick and all. It will hopefully be finished this weekend and they will be out on grass like the others.

Sorry I haven't been online...glad to see others had such good and useful advice...
Chickens will peck each other...yes out of boredom...close quarters,,,lacking protein..lice or bugs..and.seeing any bare red skin...they go wild after the color red...You can get anything to dab on their pecked skin that isn't red,,,,I use Furall...it is mainly used on cows but good for chickens also..
I never have tried it...but have been told that you can hand a head of cabbage in their pen and they will peck at it and take their mind off each other...
Put a red light in their pen at night ...not a heat lamp and that seems to calm them also...Some of my chickens have bare backs right now....Randy roosters...lol..
Things will get better and glad to hear they are...Have a good one...MissKItty

I once read that if you put pine tar on a sore on a chicken that it helps. A friend tried this and it worked. The chicken stopped pecking at it. Would this help?

Yes it will....Anything like that...the furall sure does...get it at the feed store-MissKitty

Cat food is a cheap source of protein.

A lady at Church told me she feeds it every spring to boost egg production, I gave it a go, it did boost egg prouction, and given a choice my chickens picked it over the laying mesh I was feeding!

Don't know if it will help with peeking...

As you said I have had a oppossum do it.
