In the Brooder
We have 6 pullets (2 Barred Rocks, 2 Golden Lace, 1 Easter Egger, and 1 Sapphire Sky/Gem). Everyone has been getting along well; the occasional pecking happens or a short chase away, but nothing that causes injury or makes hens avoid one another.. Until Sunday. We noticed on Sunday that Lavender (our EE) was hiding in the coop and away from everyone. We observed what was happening. Sunshine (our goldie) was chasing her around almost non-stop to the point that Lavender avoided Sunshine completely. Our goldies (Sunshine and Marigold) are almost inseparable, but Marigold doesn't do anything towards Lavender. Our goldies have been sleeping on the corner at night and not roosting; however, some day last week, they were roosting on the bar with everyone else.. I noticed that Marigold was next to Lavender, and Sunshine was at the other end.. I noticed Sunshine tried to nudge Lavender from her spot, but she did not move. Then the goldies went back to sleeping on the floor in the corner.
Lavender is obviously at the bottom of the pecking order and is very timid. However, none of the other girls are like that at all towards her. So, after we noticed that Lavender was in obvious distress from Sunshine, we crated Sunshine. Sunshine is in the runner, in her own crate with food/water, and almost immediately, Lavender came out and was doing her usual stuff. Monday and yesterday, Sunshine was crated for doing the same chasing.. Yesterday evening (it is very hot where we are), I let her out, and she didn't chase Lavender at all; however, that changed this morning, and she chased/pulled feathers. Sunshine also does a hackle flash at us and does not like us holding her at all. We also saw that she was doing a sort of charge attack where her body was low to the ground and she ran up towards Marigold (our other goldie). I hate putting her in the crate, but I also hate seeing Lavender hiding and darting away from Sunshine, even when she isn't chasing her.. I understand pecking order chicken stuff will happen, but I feel Lavender was bullied, and Sunshine was excessively aggressive. (or am I wrong?) Lavender does not fight back/stand her ground. I just do not want anyone seriously hurt, or Lavender not getting food/water/dust bath.
Please give us advice on what to do. My heart cannot take it.
Thanks y'all.
