We've had our 2 barred rocks and 1 rir since around July. Last month we lost my daughter's leghorn when a coop door got accidentally left open by DH and the dog got her pinned down, giving her a heart attack. So, we got and aracauna and 2 aracauna mixes. 2 of them (the aracauna and one of the mixes) are small birds. Our other birds are...not small. I have to go out and put one up in the coop at night because she can't get into the pop door from the run under the coop she's so big! I expected pecking order to have to be worked out. I put the new birds in at night. The old birds are just plain vicious! The 3 new girls have been cowering in the corner of the nestbox. This morning I noticed the 2 smaller ones legs were really bloody. Thanks to these forums, I put non-pain relieving neosporin on them, isolated the birds, and headed to the feed store for some Blu-Kote (and taught the employees about its use for poultry!). Right now the aracaunas are in the coop, and the three older birds are in the shed in a doghouse since they can free range during the day. My question is how to integrate these essentially two flocks into one? I had thought of leaving the older birds in the doghouse, and each week (starting next week) adding one into the coop with the aracaunas, from best to worst temperment. Would that work? Or am I missing something? Hubby will kill me if I need to build another coop so close to winter! Help me keep the marriage peaceful...before I'm putting an air mattress in the coop and snuggling with some hens at bedtime!
