we just finished our coop and run. chickens are out in teh run all day now and soooo happy. but at night when when want to get them back in coop and lock them safely in for the night the chicks (2 1/2 months) won't go up ramp and into coop. we have tried everything. we added more rungs on ramp, strawberry bribes etc. ramp is a little steep. now we have to chase and catch each one every night--any ideas??? or do they just grow into knowing how to go in at night???
