I have a total of six chickens; three are 2 years old; the other three are about 10 months. They were kept separate all winter - now I want to integrate. Meanwhile, one of the three older chickens got really beat up by the other two in the winter quarters. She's had a lot of feathers pulled, she's lost weight and she's weak. So I've been having three separate chicken quarters - the one beat up one by herself. The two older ones, by themselves, and then the three younger ones by themselves. It's crazy! So I tried to put everyone together. I put rooster booster pick-no-more on the weak one, and then put them all together - lots of space in electric poultry netting area and coop. The two older ones have been extremely aggressive; dominating the weak one and all three younger ones for two days with lots of fighting and intimidation. Finally I couldn't stand it any more, so the two agressive ones are back in the pen in the barn, and the weak one is out with the three youngsters in the coop (with poultry netting run). I'm going to buy a dog crate and try to get the two agressive older ones introduced slowly by sight, but separate. I don't know what to do about the weak one. I don't want to separate her again because I'm afraid I'll never get her integrated but I'm worried how she'll do with the three youngsters. Any suggestions? Also, what do I do at night? I can put the two agressive ones in the dog crate but we have weasel issues here and I'm afraid to have them just in the crate at night. Can I put them to roost all together and then split them up just during the day or is that a bad idea? Please help! I'm exhausted and depressed about how this has gone and my husband is upset with me because of all the hassle and worry. Any suggestions would be so appreciated! Desperate in Vermont.
