I have 4 point of lay (but not yet laying -they look close though) pullets and 2 older hens (2 years old) they are in separate coops. During the day I have put the pullets in a little baby yard covered with chicken wire, and let the hens free range, and they seem to have gotten used to each other. Early on there was a lot of posturing but last time I looked one hen was ignoring them and the other was eating grass right up next to the baby yard and neither side was protesting. Do I just put them all in together one night? Also, the pullets are not roosting - they are sleeping on the floor of the coop (but they've only been in there one night so far). My last question is, I know you aren't supposed to put them on layer pellet until they lay because they can't get rid of the added calcium in layer feed- but the older laying chickens need the layer feed... not sure what to do as I won't be able to separate feed.. I can keep them separate until the pullets start laying, but I would love to put them all together in the new coop. Thoughts?
