I have two 13 week old pullets who are now being introduced in with 3 big girls. What I have been doing this week so far is keeping the pullets in the coop/run during the day while the bigger ones free range all day. At night, I let the big ones in. The little ones try to get right up on the roost with them- they are tenacious about it!- but they end up sleeping below in the nesting boxes because the elder ones make them. In the a.m., I go out early and let the big ones out as soon as they come off their roost (otherwise the little ones are not allowed to eat, even though I have 4 feeding stations.) Should I be giving the whole group more time together? I just hate seeing the little ones picked on and pecked on. They have all been in each others nighttime company for about a week now (and were in separate cages at all times before that). Should I be be letting them "work it out" more and not letting the big ones out all day? Or is it good to wait until the little ones are bigger and more the same size as the elders? I don't want to let the little ones free range with the group yet as I can not catch them- they are very afraid of me- and the yard is big. Issue #2 is that one of the pullets is being picked on in her back tail feathers by the other pullet. It doesn't look horrible- not all bloody- but definitley raw and a lack of feathers on the tail. Should I be medicating this? Thanks for your help!
