i have 2 hens, one serama, and one olandsk dwarf. these two hens were in the same cage together for most of their lives with no problems. long story short i gave the olandsk dwarf to a women who wanted to see if she can handle raising chickens. she took the olandsk dwarf about 2 1/2 weeks ago. when i brought her back the serama and her started pecking each other. i quickly separated them and put the olandsk dwarf in a cage next to the run were the serama can see her. the olandsk dwarf cooled down, but the serama is still agressive towards her. the serama is not taking her eyes off of her. the serama is 13 weeks old and the olandsk dwarf is 12 weeks old. how can i put them back together in the coop?
