New Flock - Aggressive Chickens

Hi all -

Though I grew up with chickens it has been 20 years since the farm and several hundred free rangers. Now I live in a very small town in Colorado and just built a coop out of a playhouse. It's a nice size coop. 18 sq ft inside, 4' ceiling, 3 nesting boxes. and a 65 sq. ft run outside with a 6' ceiling.

We just got four 18 month old hens from a gal down the way who is trying to thin her 250 chicken flock. We have 2 golden buffs, 1 leghorn, and 1 ancona.I should clarify - - I *think* we have 2 golden buffs - -one definitely is and the other is extremely similar to the first but has a black cowl or neck.

Anyway - - we've had them for 3 days - and we got them when they were molting. We had 4 eggs on day 2 and thought all is well. But then the leghorn starting pecking the 2nd GB (Rainy) - and really aggressively at that. To the point where Rainy hides in one of the nesting boxes and won't come out even to eat or drink. Then the leghorn starting pecking the other 2 birds as well if Rainy was anywhere in the vicinity. If Rainy doesn't come out of the coop, the leghorn pretty much leaves the other 2 hens alone. So right now I have Rainy *free-ranging* outside of the run and the leghorn is for the most part leaving the other 2 hens alone.If I put Rainy back in the coop - all of the other 3 attack her - - constantly.

I just got some meat based feed this morning and all 4 have had their fill but I still can't put all 4 birds together. I understand the pecking order thing but this seems much more aggressive than that and is non-stop - -

BTW - -like I said before - -these chickens come from a free-range situation.

I have lots of thoughts on what to do (e.g., currently building a tractor but not sure which bird to put in it, slaughtering the leghorn, slaughtering the GB). I don't know. I do know that the ancona and the 1st GB both have been wanting to lay but seem stressed out. I also know that whenever one of them goes to lay there is a 50/50 probability that the leghorn will follow them up to the coop and hover around them. I should also say that although we had 4 eggs in one day - -one of them had been pecked and I am 99% certain it was the leghorn that did the pecking.

I also have only 1 roost in the coop - which only the arcuna sleeps on even though it is 4 feet long and 18" off te floor of the coop. Should I put another roost in higher up?

Any thoughts would be greatly appreciated!

Thanks,

Tim

 

I should also add - that I just discovered a bit more about the leghorn. I said before that the leghorn hovers around anybody trying to lay and that I found one of our 4 eggs pecked. The acuna has been trying to lay all morning and every time she goes to a nest to lay the leghorn follows her and runs her of her nesting box. I finally shooshed the leghorn back into the run and closed the coop door and guess what - the acuna laid her egg. It took her about half an hour and the entire time the leghorn was at the top of the ramp, at the door, clucking to get in the coop. Can the leghorn have a predisposition for eating/pecking eggs? Should I just *do something* with the leghorn? Will isolating her help? If it weren't that one of my kids had named that particular bird - -we would already have soup stock going.

Thanks,

Tim
